State the factors on which the magnitude of the magnetic field due to a current-carrying conductor depends and how it depends.

Answer»

Solution :The magnetic field at a POINT DUE to a CURRENT-carrying conductor depends on the current through the conductor and the distance of the point from the conductor .
(1) The magnitude of the magnetic field produced at a given point is directlyproportional to the magnitude of the current PASSING through the conductor .
(2) The magnitude of the magnetic field produced by a given current in the conductor decreases as the distance from the conductor increases.
