How to Generate Electricity With Magnets
According to "Fundamentals of Physics," by David Halliday and Robert Resnick, when a closed wire cuts a magnet's field lines, the electrons in the wire experience an electromotive force (emf). From this principal, you can generate electrici... Read More »

How Are Magnets & Electricity Related?
Magnetism and electricity are two of the more mysterious phenomena of the everyday world. Electricity is the movement of submicroscopic charged particles through a material. This flow of charges, or "current," moving through the wires of a ... Read More »

What Is an Electric Magnet Generator?
Magnets are objects that generate magnetic fields. These magnetic fields can attract some kinds of metal to the magnets. Magnets also interact, attracting or repelling each other depending on their relative orientation. In addition, magnets... Read More »
