From our electrostatics unit, we know that electricity can be defined as simply as the movement and transfer of electrons. we also know that certain magnets repel and attract due to a magnetic field (B). A magnetic field exerts a force on moving charges. Also, any moving charge has a magnetic field that surrounds it. In the photo below, a horse shoe magnet is underneath a piece of paper in which we sprinkled powdered iron onto. The lines show the magnetic field:
The magnetic field that surrounds a magnet applies a force to the electrons in an object which causes them to flow, or an increase in current. This increase in current results in more electricity.
