Which of the following would increase the strength of an electromagnet? check all that apply.

a. increasing the current flowing through the wire
b. increasing the number of loops of wire
c. straightening the wire
d. putting a plastic comb inside the loops of wire
e. putting a piece of candy in the middle.

The correct statements are ; A and B.

Explanation:

The strength of the magnetic field(B) in an electromagnet can be calculated using formula:

= Relative permeability

N = number of turns

I = Current in the wire of the solenoid

L = length of the solenoid or electromagnetic

As we can see from the formula:

So, by increasing the turns and increasing current flowing through wire one can increase the strength of an electromagnet.

Hence, the correct statements are ; A and B.
