Is there magnetic field inside a magnet?

As can be visualized with the magnetic field lines, the magnetic field is strongest inside the magnetic material. 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.

How does a bar magnet produce a magnetic field?

Magnets are different because the molecules in magnets are arranged so that their electrons spin in the same direction. This arrangement and movement creates a magnetic force that flows out from a north-seeking pole and from a south-seeking pole. This magnetic force creates a magnetic field around a magnet.

What is the magnetic field inside a magnet?

The magnetic field lines of a simple magnet are shown in the picture below. They point from the north pole to the south pole. However, the magnetic field lines do not just end at the tip of the magnet. They go right through it, so that inside the magnet the magnetic field points from the south pole to the north pole.

What is a magnetic field made of?

Magnetic fields are produced by moving electric charges. Everything is made up of atoms, and each atom has a nucleus made of neutrons and protons with electrons that orbit around the nucleus. Since the orbiting electrons ≠are tiny moving charges, a small magnetic field is created around each atom.

Where is the weakest area of magnetism on a magnet?

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.

Is electromagnet a permanent magnet?

The main advantage of an electromagnet over a permanent magnet is that the magnetic field can be quickly changed by controlling the amount of electric current in the winding. However, unlike a permanent magnet that needs no power, an electromagnet requires a continuous supply of current to maintain the magnetic field.

Where is magnetic field strongest?


Where is the strongest magnetic field in a coil?

The resultant static magnetic field with a north pole at one end and a south pole at the other is uniform and a lot more stronger in the centre of the coil than around the exterior.

How magnetic field is created?

Any current (movement of electrical charge) will create a magnetic field. Certain materials are capable of realigning the angular momentum of their electrons, and iron is one of them. When the angular momentum of electrons gets aligned, an external magnetic field is created.

Are photons affected by magnetic fields?

According to theory of properties of photon, they can not be affected by electric and magnetic fields and it is neutral. But Electromagnetic waves contain electric and magnetic fields .

Why can’t 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 does magnetic field do for Earth?

The Earth’s magnetic field serves to deflect most of the solar wind, whose charged particles would otherwise strip away the ozone layer that protects the Earth from harmful ultraviolet radiation. One stripping mechanism is for gas to be caught in bubbles of magnetic field, which are ripped off by solar winds.

Which shape of magnet is the strongest?

horseshoe shape

Where is Earth magnetic field weakest?


What is the weakest part of a magnetic field?

The magnetic field is weakest along the surface in the middle of the side of the magnet. This is a close-up of the field at the North pole.
