Question

What is solenoid? Draw the pattetn of magnetic field lines of a solenoid through which a steady current flows what does the pattern of field line iside tje solenoid indicate?

Answer 1

a solenoid is a magnet made up of by wrapping up the long insulated copper wire on a long hollow cylinder.

Magnetic field lines of solenoid are jist the same as bar magnet

inside the magnet the field lines are parallel to one another thus making magnetic field uniform inside the solenoid
