ELECTRICITY MAGNETISM
MAGNETISMThere are several relationships between electricity and magnetism. We will explore them one by one. The first relationship we will discuss is how current flowing through a wire creates a magnetic field. A steady current creates a steady magnetic field like that created by a magnet. Electro-Magnet We can create an electro-magnet by wrapping many turns of wire on a core, then causing an
