The hypothesis is that the coil with many turns will have the highest voltage, so the greater the number of turns, the higher the voltage.

You will need to build an electromagnet with a screwdriver, magnets, and insulated wire. Then, you will measure the voltage of the electromagnet with a digital voltmeter.

You will need an electric screwdriver, 4 magnets, masking tape, 3 hollow boxes, insulated wire, a paper cutter, 2 crocodile clips, a digital voltmeter, and a pair of scissors.

The results show that increasing the number of turns in an electromagnet's coil will result in an increase in the induced voltage caused by the changing magnetic field. The graph of the results clearly shows that the voltage increases as the number of turns increases.

This science project is interesting because it demonstrates the principles of electromagnetic induction and how it can be used to measure voltage. It also shows how the voltage of an electromagnet can be increased by increasing the number of turns in the coil.

Experiment variations include changing the speed of the screwdriver and rotating the coil instead of the magnets.
