Magnetic field outside a straight conductor

Magnetic field component By of two parallel conductors on the x-axis as a function of the distance from one conductor, if the current in both conductors is in the same direction.

Principle

Teslameter, digital

A current which flows through one or two neighbouring straight conductors produces a magnetic field around them. The dependences of these magnetic fields on the distance from the conductor and on the current are determined. Tasks Determination of the magnetic field 1. of a straight conductor as a function of the current, 2. of a straight conductor as a function of the distance from the conductor, 3. of two parallel conductors, in which the current is flowing in the same direction, as a function of the distance from one conductor on the line joining the two conductors, 4. of two parallel conductors, in which the current is flowing in opposite directions, as a function of the distance from one conductor on the line joining the two conductors.
