Question

on what factors does the strength of an electromagnet depend on

Answer 1

it depends on how strong the electric current flowing through the conductor is pass

Answer 2

1.) It is directly proportional to the:

(i.) current flowing through the conductor

B ∝ I

(ii.) number of turns in the coil.

B ∝ n

2.) It is inversely proportional to the:

(i.) Radius of the circular wire

B ∝ 1/r

Hope this helps you
