Question

The number of turns in a solenoid is increased 5 times without any increase in current how is its magnetic intensity affected

Answer 1

Answer:

B is the magnetic field and N is the number of turns of the coil of the solenoid. I am the current. Hence if current increases 5 folds, the magnetic intensity B also increases 5 times because the magnetic intensity and current, I.e. B and I respectively are directly proportional to each other
