Why is it necessary to use at least one electromagnet in a motor instead of using only permanent magnets?

Because as you might already know electromagnets use a conductive metal and electricity to make the said electromagnet. So what do you get if you use the electromagnet and move it through coiled wire. The magnetism makes a electrical current thus making your motor.

A correct answer (sample response) is:

Generators are important because they can provide electricity during a power outage. This is especially important at hospitals, so doctors and nurses can continue to treat patients during a power outage.
