Question

Name two factors on which the strength of magnetic field of an electromagnet depends ?

Solution

The magnetic field of an electromagnet (I or U-shaped) can be increased by the following two ways :

  1.  By increasing the number of turns of winding in the solenoid.
  2.  By increasing the current through the solenoid.
  Is there an error in this question or solution?
