ELECTRICIAN'S BOOK-THE EXPERIMENT OF ELECTRICITY PRODUCTION (20 MODULES SERIES&VIDEO DEMO)Rotating a coil in magnetic field

There are more ways to generate the electromotive force(EMF).

EMF is in fact a voltage.To do our experiment we need to have available magnetic field, and a coil made by copper wire.Magnetic field is going to be supply by a pair of permanent magnets. Intensity of magnetic field is a measurable parrameter and most of the time is indicate by letter B.Magnetic field intensity (B) is measured in Tesla (T).Here in this section you understand how the experiment is set-up.You have the option to achieve all modules from 1 to 20 or to choose the ones important for you in order to understand how the electricity is generated. I will encourage you to achieve the complete package and read them step by step as indicated below. Highlighted item is the one you just achieved:
