What rotates in a magnetic field?

The rotating magnetic field is the key principle in the operation of induction machines. The induction motor consists of a stator and rotor. The flux generated by the armature current reacts upon the field poles and the armature is set in rotation in a definite direction.

Which part of the Earth is responsible for generating the Earth’s magnetic field?

the Earth’s core
The crust of the Earth has some permanent magnetization, and the Earth’s core generates its own magnetic field, sustaining the main part of the field we measure at the surface.

How does the earth rotate and revolve?

As the Earth rotates, each area of its surface gets a turn to face and be warmed by the sun. Objects rotate around an axis, but revolve around other objects. So the Earth rotates around its axis as it revolves around the sun. It takes the Earth 365 days, or one year, to complete a revolution.

What force makes Earth rotate?

Earth rotates because Sun attracts the earth and thus pulls earth towards it secondly due to earths revolution around sun it tends to go away from sun in direction of the tangent hence a rotational force (torque) acts on earth and it tends to rotate.

What is rotating magnetic field explain in brief?

A rotating magnetic field is the resultant magnetic field produced by a system of coils symmetrically placed and supplied with polyphase currents. Rotating magnetic fields are often utilized for electromechanical applications, such as induction motors, electric generators and induction regulators.

What happens when you rotate a magnet?

When you rotate a magnet, you are using kinetic energy to move it. This kinetic energy can be converted to electrical energy by taking advantage of the properties of electromagnetism.

Which layer is responsible for Earth magnetic field and why?

The outer core
The outer core is responsible for Earth’s magnetic field. As Earth spins on its axis, the iron inside the liquid outer core moves around. The movement causes powerful electric currents to develop in the liquid iron itself.
