Question

3) what are the factors on which magnetic effect of current depends​

Answer 1

Answer:

The strength of an electromagnet depends on :

The current flowing in the coil. If the current in the coil is increased, the strength of electromagnet increases. The length of air gap between the poles. If we reduce the length of air gap between the poles of an electromagnet, then its strength increases.
