Question

We can increase the strength of an electromagnet by increasing the number of turns of wire on the coil and but is there any other method with the help of which we can increase the strength of an electromagnet?

• A. by decreasing the flow of current
• B. by increasing the flow of current
• C. by increasing the thickness of wire
• D. by increasing the thickness of magnet

Answer 1

The correct option is B

by increasing the flow of current

Electromagnet is a soft iron core made into a magnet by passing electric current through a coil surrounding it. There are two methods by which we can increase strength of magnetic field are: 1) By increasing the number of turns of wire in the coil. 2) By increasing the current flowing the coil
