Ceramic Magnets – High Efficiency Generator FREE PDF Download
So how do you collect the back EMF?
Lets start with the basic’s. We start with a coil of copper coated wire which is used as an electromagnet or a generator
coil. By applying 12 volts DC to the coil of wire you get a strong magnetic field, Polarity is forward and when that 12 vdc is turned off the coil produces a reversed polarity, in which the magnetic field changes also. But voltage will be lower because the 12 VDC must be pulsed (Switched on & off) at a high rate. The faster the better, So what is happening is you are getting FREE ENERGY FROM A COLLAPSING MAGNETIC FIELD. SEE fig, #1 You will need to use a diode to capture the back Emf
