A current carrying conductor, such as a metal wire, will produce a magnetic field around it because of the motion of charge within the wire itself. This motion produces or sets up a magnetic field around the wire in the form of concentric circles. 

This electromagnetic effect is described in physics by the Biot-Savart Law, an experimentally deduced inverse-square law. The effect is also described by Ampère's Law, which is derived from the Biot-Savart Law. This law relates magnetic field and current. 

Also, a magnetic field that is set up by an electrical current will produce a magnetic force. This force depends on the rate of charge transfer and the magnetic field. 

The force produced by a current-carrying wire depends on the length, the magnetic field, and the current, which is the charge flow per unit of time.

does the field produced due to the current carrying conductor exist inside the bulk of the conductor too?
