Juan makes an adjustment to an electromagnet that causes the electromagnet to lose some of its strength. what did juan most likely do?

he reduced the number of loops in the wire.

he increased the number of loops in the wire.

he reduced the length of the wire.

he increased the length of the wire.

A) he reduced the number of loops in the wire

Explanation:

the less loops made on a wire, the less strength the electromagnet has

He reduced the number of loops in the wire.

Explanation:

According to superposition principle, when you have a loop of wire next to the other, the resulting magnetic field in a particular point is the overall sum of the individual magnetic fields of each loop. So, the more loops you have, the stronger the magnetic field is.
