Magnetic field outside a straight conductor
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.
- Four different current conductors allow the observation of the magnetic field in different configurations
- Experimental setup allows the visualization of the Maxwell Equations
- No extra calibration needed, Teslameter is calibrated up to 1 T

Determination of the magnetic field
- of a straight conductor as a function of the current,
- of a straight conductor as a function of the distance from the conductor,
- 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,
- 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.
- Maxwell’s equations
- Magnetic flux
- Induction
- Superimposition of magnetic fields
- Alternating current
