Inductors
... When a length of wire is formed onto a coil, it becomes a basic inductor. Magnetic lines of force around each loop in the winding of the coil effectively add to the lines of force around the adjoining loops, forming a strong electromagnetic field within and around the coil. The unit of inductance is ...

... This is done by voltage traveling thru a fine wire coiled thousands of times around a soft iron core which produces an electro magnet and magnetic field. When the points break the circuit to earth, this stops the 10v flow and the magnetic field collapses. This is instantly converted to the large 20, ...
