Induced current. Oscilloscope trace from an electric coil,showing a current flowing at the precise moment when a magnet is dropped through the coil. Electricity is generated,or induced,when a wire moves through a magnetic field. This principle is exploited in electricity generators,which spin a coil between magnets to convert rotary motion into electrical energy | |
