Free virtual experiment
This is a virtual experiment to investigate the magnetic field produced by a coil. The number of turns on the coil can be selected. The maximum amps and voltage can be selected on the power supply and the actual amps read from a multimeter.
A magnetometer allows the reading of the deflection caused by the magnetic field.
This experiment can also determine the horizontal component of the local magnetic field due to the Earth (in the virtual laboratory of course!).
