Question: What keeps the electric motor spinning?

How does an electric motor continue to turn?

The forces on each side of the coil are in the opposite directions to one another, so the coil turns (4). The commutator reverses the current around the coil with every half turn (5) meaning that the coil is pushed in the same direction every half turn, and thus continues to rotate (6).

Why does a motor spin continuously?

When you give the coil a spin, since one side of the wire is insulated, you break the circuit briefly, so the coil continues to rotate using its momentum. When the circuit is complete again, the magnetic field once again repels the coil, so it keeps spinning.

Why does the coil rotate continuously in an electric motor?

The coil of wire is mounted in the gap between the two magnets. The split rings make electrical contact with the coil and reverse the current every half turn. When an electric current flows through the coil, a force is exerted on the coil, causing it to spin.

How an electric motor creates rotational motion?

In this invention the electric energy forces the matter to move. Basic function of an electric motor is that it’s based on at least two magnets, which create rotational motion. … The motion is based on magnetism. The device uses electromagnetic (or magnetic) forces to transfer the energy to mechanical energy.

What causes the coil to continue spinning when current is not flowing?

The permanent magnet attracts its opposite pole on the coil and repels its like pole, causing the coil to spin. … By painting half of one end black, you prevent current from flowing for half of each spin.

Does the motor rotate continuously when there is current?

With the commutator in place, when electricity flows through the circuit, the coil will rotate continually in the same direction.

What causes a copper wire motor to loop?

The coil is made of copper wire – because it is such an excellent conductor (see conducting properties). It is wound onto an armature. The coil becomes an electromagnet when a current flows through it. … They produce a steady magentic field so that the coil will turn when a current flows in it.
