Question

Solenoid
(a) Complete the diagram of magnetic lines of force passing through a solenoid.
(b) Define solenoid.
(c) What is the nature of the magnetic field inside the solenoid?​

Answer 1

Answer:

b)A coil with many circular close turns of insulated copper wire (like a cylinder as shown above) is a solenoid. One end of such a solenoid behaves like the north pole and the other as a south pole. Therefore magnetic field due to current in the solenoid is similar to a bar magnet.

c)Field lines are parallel straight lines inside solenoid

It means magnetic field is same at all points inside the solenoid, that is, magnetic field is uniform inside a solenoid.
