Question

why solenoid behave like a bar

Answer 1

Ans: Solenoid behave like a bar magnet because the magnetic field lines are same as of bar magnet .

Answer 2

[Tex]\textbf{ Magnetic field lines are produced around the solenoid when a current is allowed to flow through it. The magnetic field produced by it is similar to the magnetic field of a bar magnet. ... Hence, one end of the solenoid behaves as a north pole and the other end behaves as a south pole}
