... verify than the corresponding electric law. It is not even possible to define the most fundamental property of a permanent magnet: i.e. that the total magnetic charge of each magnet is zero. Instead, there only remains the rather pale claim that a magnet has (at least) two poles. For a normal bar ma ...

... What is an Electromagnet? When an electric current is passed through a coil of wire wrapped around a metal core, a very strong magnetic field is produced. This is called an electromagnet. The more coils wrapped around the core, the stronger the magnetic field that is produced. This stronger mag ...
