Coils
As we know from earlier pages, electron moving through a wire causes an electromagnetic field around the wire. If we wrap the wire in a coil then that intensifies the magnetic field and that magnetic field can be put to many uses.
Coils have some important properties to note. They resist rapid changes in the current flow. Steady current pass through freely.
Magnetic fields, or rather changing magnetic fields, can induce a current to flow. So current from one coil
creating a magnetic field that makes current flow in another coil.
