Question

when electric current passes through a wire it behave like

Answer 1

Maxwell Electromagnetic theory is an answer for your question.

If you pass current through a straight wire, magnetic field is formed around the wire in the form of circular rings. On the other hand, you're passing current through a circular spring-like thing (commonly, a coil) called solenoid, magnetic field is produced along its axis. so it is clear that Magnetic field is produced by moving charges (current). This is an observed phenomena and it's explained by Maxwell.

Answer 2

when electric current passes through the wire it produce the magnetic fields around the wire and wire behaves like a bar magnet.
