magnetic field?

0 ⤊

There comes an insulation with the wires in the market (normally plastic). My question is there any magnetic field present outside that insulation when current is present.

Yes. Though there are many analogies between electricity and magnetism, there is no such thing as a magnetic insulator. As a result, if a magnet field is created due to a current in the wire, the magnetic field will pass right through the insulation of the wire

Normaly as per theory, there should be a magnetic field around the coil passing electricity
