Answer 1

The strength of an electromagnet decreases when the voltage in the coils of the solenoid is decreased.

Step-by-step explanation:

The strength of an electromagnet decreases when the voltage in the coils of the solenoid is decreased.

An electromagnet works by running an electric current through a coil of wire. The strength of the magnetic field produced by the electromagnet is directly proportional to the current flowing through the wire. So, when the voltage in the coils of the solenoid is decreased, the current flowing through the wire decreases, resulting in a decrease in the strength of the electromagnet.

For example, if you have a solenoid with a high voltage applied to it, it will create a strong magnetic field and have a strong lifting power. But if you decrease the voltage, the magnetic field and the lifting power will decrease as well.
