... cannot change a charged particle’s potential energy or electric potential. But electric fields can do work. This equation shows that a changing magnetic flux induces an electric field, which can change a charged particle’s potential energy. This induced electric field is responsible for induced emf. ...

... The measured “fields” are measured and known to move at the speed of light for the dielectric. It is an accident of math that 2+2 = 22 • “double the electric field has led to four times the energy because the formula for energy contains the square of the voltage. This quadrupling is untrue, because ...

... metal core a strong electromagnet can be made. When attached to an electrical source it will produce a strong magnetic field. To keep this electromagnet spinning in a magnetic field, the direction that the current is traveling through the coil must be switched. This is accomplished by with a gap, wh ...
