Electromagnets and Induction
... Motors that run on AC electricity are easier to make because the current switches direction all by itself. All electric motors must have three parts: 1. Rotor 2. Fixed Magnet 3. Commutator ...

Electromagnetic Induction(EMI)
... with magnitude B = 0.60 T, directed into the page. We lay a metal rod with length L = 0.10 m across the two arms of the conductor, forming a conducting loop, and move the rod to the right with constant speed v = 2.5 m/s. What is the magnitude of the resulting emf? ...
