How a Generator Works When an electric current flows through a wire, it generates a three-dimensional magnetic force field around the wire, similar to that surrounding a bar magnet. Magnets are ...

which keeps the liquid metal moving through the magnetic field. The so-called Coriolis force also plays a role in sustaining the geomagnetic dynamo. Our planet's spinning motion causes the moving ...

A – The coil is at 0°. The coil is moving parallel to the direction of the magnetic field, so no potential difference is induced. B – The coil is at 90°. The coil is moving at 90° to the ...

increasing the rate of rotation increasing the strength of the magnetic field increasing the number of turns on the coil The diagram shows four different positions of the coil in a dynamo ...
