# the ends of a magnet where the forces are the strongest are called magnetic

magnetic poles

## Where on a magnet is the magnetic force the strongest?

poles
It is strongest at the poles. So, what are magnetic poles? Magnetic poles are opposite ends of a magnet where the magnetic field is strongest.

## What is the strongest magnet called?

neodymium
The strongest permanent magnets in the world are neodymium (Nd) magnets, they are made from magnetic material made from an alloy of neodymium, iron and boron to form the Nd2Fe14B structure.

## Which part of a magnet is strong?

poles
The main strength of a magnet is at the poles, i.e. the North and South poles, which lie at each end of a magnet, or each side of a circular magnet.

## Where are the magnetic fields strongest near a bar magnet?

poles
The strongest external magnetic fields are near the poles. A magnetic north pole will attract the south pole of another magnet, and repel a north pole. The magnetic field lines of a bar magnet can be traced out with the use of a compass.

## How strong is the strongest magnet?

The MagLab’s DC magnet maintains a steady 45 Tesla of field strength, which until very recently was the strongest continuous magnetic field produced in the world.

## What makes a strong magnet?

The more powerful the external magnetic field that is applied, the greater the magnetization that results. … Those with a high magnetic permeability (which is a measurement of how responsive they are to magnetic fields) make the strongest magnets. For this reason, pure iron is used to make some of the strongest magnets.

## Where is the magnetic force the weakest?

center
The magnetic field is weakest at the center and strongest between the two poles just outside the bar magnet. The magnetic field lines are densest at the center and least dense between the two poles just outside the bar magnet.

## Which ends of magnets attract?

The end that faces the north is called the north-seeking pole, or north pole, of the magnet. The other end is called the south pole. When two magnets are brought together, the opposite poles will attract one another, but the like poles will repel one another.

## Where is the force of magnetic lines strongest in a bar magnet quizlet?

The magnetic forces are strongest near the ends, or magnetic poles of the magnets. If a bar magnet is suspended it turns freely, the north end will point north. Like poles repel. Unlike poles attract.

## How strong is magnetic force?

Magnetic fields that surpass about a billion Gauss are so strong that they compress atoms to tiny needles, destroying the ordinary chemical bonds that bind atoms into molecules, and making chemistry as we know it impossible.

## When magnets are closer together the force of magnetism is stronger?

The magnetic field magnitude is proportional to the density of the lines. The closer together the field lines, the stronger the magnetic field. The more spread out they are, the weaker the magnetic field.

## What is the strongest magnet in the world used for?

Engineers in the U.S. are preparing to ship the first part of the world’s most powerful magnet to France, where it will help power a state-of-the-art nuclear fusion reactor. The magnet, known as the central solenoid, will make up the heart of the world’s largest fusion reactor, ITER, which means “the way” in Latin.

## What has the strongest magnetic pull?

The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.

## What has the strongest magnetic force of an object in the universe?

Ultra-powerful magnetic neutron stars play hide-and-seek with astronomers. … It can generate the most intense magnetic field observed in the Universe. The field strength of a magnetar is one thousand trillion times stronger than Earth’s and is so intense that it heats the surface to 18 million degrees Fahrenheit.

## What affects the strength of magnetic forces?

Explanation: The answer is “all of these affect the strength of a magnet” The proximity to the object, the size of the object, the material of the object it is sticking to, and the temperature of the object all affect magnetic pull. … North and south poles of magnets are attracted to each other.

## How do you know where the magnetic field is the strongest?

the closer the lines, the stronger the magnetic field (so the magnetic field from a bar magnet is strongest closest to the poles) the lines have arrowheads to show the direction of the force exerted by a magnetic north pole.

## Where is the field the strongest Where is the field the weakest?

Field-Line Patterns

The relative magnitude of the electric field is proportional to the density of the field lines. Where the field lines are close together the field is strongest; where the field lines are far apart the field is weakest.

## Where is the pushing or pulling force of a magnet strongest?

When two magnets are close, they create pushing or pulling forces on one another. These forces are strongest at the ends of the magnets. The two ends of a magnet are known as the north pole and the south pole.

## Which of the following refers to ends of a magnet?

A magnet has two ends called poles; one end is the north pole and the other is the south pole. A north pole will attract a south pole; the magnets pull on each other.

## What are the names given to the two ends of a magnet Why are they named thus?

Experimentation shows that all magnets have two poles. If freely suspended, one pole will point toward the north. The two poles are thus named the north magnetic pole and the south magnetic pole (or more properly, north-seeking and south-seeking poles, for the attractions in those directions).

## Can you make magnets stronger?

If you can find a very strong magnet, repeatedly rub it across your weakened magnet. The strong magnet will realign the magnetic domains inside the weakened magnet [source: Luminaltech]. Magnet stacking One way to make weak magnets stronger is by stacking more of them together.

## When freely swinging one end of a magnet should always point to the East?

Importance of Magnetic Poles

One end of any bar magnet will always want to point north if it is freely suspended. This is called the north-seeking pole of the magnet, or simply the north pole. The opposite end is called the south pole.

## What is the region of magnetic force around a magnet?

The magnetic field is the area around a magnet that has magnetic force. All magnets have north and south poles. Opposite poles are attracted to each other, while the same poles repel each other.

## Where do magnetic field lines cross?

Magnetic field lines can never cross, meaning that the field is unique at any point in space. Magnetic field lines are continuous, forming closed loops without beginning or end. They go from the north pole to the south pole.

## What is the strength of the Earth’s magnetic field?

The Earth’s magnetic field intensity is roughly between 25,000 – 65,000 nT (. 25 – . 65 gauss). Magnetic declination is the angle between magnetic north and true north.

## Is magnetic or electric force stronger?

The one created by electric field is independent form particle velocity, while the Lorentz force is proportional to particle velocity. Thus at v=0 the electric part of force acting on particle is infinitely stronger than magnetic part.

## Would you expect magnetic fields to be stronger closer to the magnet or farther away?

We measure a magnetic field by its strength and by the direction it points. … The closer you stand to a magnet, the stronger the magnetic field will be. The farther away you are from a magnet, the weaker the magnetic field becomes.

## What force is a magnetic force?

What is the magnetic force? The magnetic force is a consequence of the electromagnetic force, one of the four fundamental forces of nature, and is caused by the motion of charges. Two objects containing charge with the same direction of motion have a magnetic attraction force between them.

## Is the strongest and the most powerful magnet on the earth?

The Applied Magnets Super Strong Neodymium Magnet is one of the world’s strongest and most powerful rare earth magnets.

## What’s the strongest magnetic field ever created?

That is far and away the most powerful magnetic field ever detected in the universe – for reference, the strongest magnetic field created in the lab so far is a “mere” 1,200 Tesla.

## What is the most magnetic object in the universe?

A Magnetar has a magnetic field as intense as 10¹⁵ Gauss, making them the most magnetic objects in the Universe.

## How strong is a 1 Tesla magnet?

10,000 gauss
Another unit of measure commonly used with magnets is the gauss (1 Tesla = 10,000 gauss). The magnets in use today in MRI are in the 0.5-Tesla to 3.0-Tesla range, or 5,000 to 30,000 gauss. Extremely powerful magnets — up to 60 Tesla — are used in research.

## Can a magnet lift a car?

The body of the car is made up of metals which are magnetic in nature. As time passes, the metal loses in weight from the body of the car. … So, the strong magnet can overcome the gravitational force acting on the car and thus lifting the car from the car.
