Question

How does the magnetic field increase when we increase the number of coils in an electromagnet?

Answer 1

Dear student!

We know that,the magnetic field is created by moving electrons so as the more electrons are moving, the stronger the magnetic field would be.

Hence, if we increase the no. of coils in the wire, the extra given length of wire contains a certain number of electrons.

If a solenoid is made with more "turns" or "wraps" of wire, then it must create a stronger magnetic field due to more no. of electrons present in the system
