Solution

The correct option is C solenoid
Given: Magnetic field produced due to a bar magnet
Solution: Magnetic field produced due to current through a solenoid is similar to that of produced by a bar magnet because:
One end of solenoid behaves as north pole and another as south pole just as a bar magnet
Parallel straight field lines inside the solenoid is similar to that of a bar magnet.
Hence the correct option is C
