Question

a current carrying solenoid is stretched to increase the distance between the coils. what is the change occur in the magnetic field?​

Answer 1

Explanation:

When the current in coil A is changed, the magnetic field around it also changes. As the coil B is placed very close to the coil A, the magnetic field lines around B coil also changes due to this as current is induced in it. (i) magnetic field produced around a straight conductor carrying current
