Question

Answer the following questions in the essay box below.

Why does the coil keep spinning?
Which way is electricity flowing?

Answer 1

The coil keeps spinning because of the interaction between the magnetic field generated by the flow of electricity in the coil and the magnetic field of the permanent magnet surrounding it. This interaction creates a force that causes the coil to rotate continuously.

As for the direction of the electricity flow, it depends on the design of the coil and the direction of the magnetic field. If the coil is connected to a direct current (DC) source, the electricity will flow in a single direction. If the coil is connected to an alternating current (AC) source, the direction of the electricity flow will change periodically, typically many times per second.

In general, the direction of the electricity flow can be determined using Faraday's law of electromagnetic induction, which states that a changing magnetic field will induce an electromotive force (EMF) in a conductor, which will cause electricity to flow in the conductor. The direction of the induced EMF and the resulting electricity flow will depend on the direction of the changing magnetic field and the direction of the coil.

Step-by-step explanation:

Answer 2

The inertia of the rotating coil carries it through half of a turn, past the insulating paint. When the electric current starts to flow again, the twisting force is in the same direction as it was before. The coil continues to rotate in the same direction.

The permanent magnets exert forces on the electrical currents flowing through the loop of wire.
