GEOLOGY

Detailed explanation-1: -The strength of an electromagnet can be increased by increasing the number of loops of wire around the iron core and by increasing the current or voltage.

Detailed explanation-2: -We can say that, the strength of the electromagnet is directly proportional to the number of turns in the coil. If you double the number of turns, you double the strength of the electromagnet.

Detailed explanation-3: -what happens to the strength of an electromagnet when the number of coils in the solenoid is decreased? is decreased, the strength of the electromagnet will decrease. This is a modal window.

Detailed explanation-4: -Increasing the number of coils adds more field lines and makes for a stronger electromagnetic field. As the number of loops of wire increases, the strength of the electromagnetic field increases.

Detailed explanation-5: -Increase the number of coil turns. Increase the current flowing through the coil. Wrap the coil tightly around the iron piece. Increase the current or voltage.
