Question

Increasing the number of loops in a electromagnet or solenoid will cause it to be stronger

True or false?

Answer 1

True

The electromagnet will become stronger if we add more coils because there are more field lines in a loop then there is in a straight piece of wire. In a solenoid there are a lot of loops and they are concentrated in the middle, as more loops are added the field lines get larger, therefore making the electromagnet stronger.
