... electric charge that regularly reverses its direction. Resistance is opposition to the flow of electric charges in an electric current as it travels through matter. The SI unit for resistance is the ohm. Resistance occurs because moving electrons in current bump into atoms of matter. Resistance redu ...

Maxwell`s Equations, Part V
... infinitesimal amount of path. In this case, the “circulation” is defined as the “electromotive force”, or emf. What is this force doing? Why, causing charges to move, of course! As such, it is doing work, and our arguments using work in the sections above are all valid here. What Faraday found exper ...

... In 1269 a French scholar, Pelerin de Maricourt, also known by his Latin name of Petrus Peregrinus de Maricourt, was taking part in the battle siege of an Italian city. As the action was very slow and dull he wrote a letter to a friend describing his study of magnets. In this letter he described the ...

The ends of the housing can be detached from the body and contain bearings to support the rotating parts at each end. The main housing acts as the Stator. This is the static part of the motor which is fixed ...
