i know that a current loop creates some kind of a short bar magnet ,
but how ?
i mean in a short bar magnet , the magnetic field leaves the north pole and goes towards the south pole Of the MAGNET itself , but in the case of the solenoid or a coil , it just looks as if the magnetic field arises in air , do air molecules align themselves such as they become a magnetic bar ? or does the current just arise a magnetic circular field around the wire ?
