Magnetic Fields
... It is important to note that magnetic fields are force fields and therefore we need to represent the lines as arrows. In fact we define the direction of a magnetic field as the direction a compass would point in that field. In a permanent magnet these lines go from north to south. ...

Magnets and Electricity
... a coil of more wire makes a strong magnet. A coil of current-conducting wire wrapped around an iron bar makes an even stronger magnet. Around the coil is a magnetic field much like the one around a bar magnet. But a bar magnet is always magnetized, while a coil wrapped around an iron bar is a magnet ...

Motors and Generators
... Faraday also showed that moving a magnet near a coil could generate an electric current in the coil, with the magnitude of the induced current depending on the speed at which the magnet is moving towards or away from the coil. These discoveries led to Faraday’s conclusion that a current can be induc ...
