Question: How does an electric motor work a level?

A-level Physics (Advancing Physics)/Motors. Just as a moving magnetic field induces current in conductors, a changing current in a magnetic field induces motion. When this motion is used to ensure that the current keeps changing relative to the magnetic field, the motion will continue, and so we have an electric motor.

How does an electric motor work physics?

A simple electric motor can be built using a coil of wire that is free to rotate between two opposite magnetic poles. When an electric current flows through the coil, the coil experiences a force and moves. … When the electric current changes direction, the same end of the electromagnet becomes its south pole.

How does an electric motor work GCSE?

When the current is flowing in the coil at 90o to the direction of the magnetic field: The current creates a magnetic field around the coil. The magnetic field produced around the coil interacts with the field produced by the magnets.

What is the basic principle of an electric motor?

The electric motor works on the principle of magnetic effects of current. Its principle is when a rectangular coil is placed in a magnetic field and current is passed through it, the coil rotates as a result of the forces acting on the coil.

What is the difference between an electric motor and an electric generator?

An electric motor converts electrical energy into mechanical or kinetic energy, whereas the electric generator transforms the electric energy into mechanical/kinetic energy.

How does a motor create electricity?

An electric motor converts electrical energy into physical movement. Electric motors generate magnetic fields with electric current through a coil. The magnetic field then causes a force with a magnet that causes movement or spinning that runs the motor. Electric motors are used in all sorts of applications.

Why will a motor not work without a commutator?

No, a direct current motor cannot run without a commutator because there is no induced electromotive force inside the armature. The commutator plays the function of supplying current to the armature from the brush. That is why the armature removed will not supply the motor. Further, it will stop the running.

What are the three basic parts of an electric generator?

No matter the type of motor, there are three basic parts: a stator, a commutator, and a rotor.
