Right Hand Rule Study Sheet
... A solenoid creates a magnetic field down its center. If a piece of iron is slipped into the solenoid it becomes a stronger electromagnet. This Right Hand Rule can be used to determine the polarity of an electromagnet. Right Hand Rule #3 A current-carrying wire experiences forces when placed in a mag ...

... the iron. Eddy currents are circulatory currents induced in the metal by the changing magnetic field. These currents produce an undesirable by-product—heat in the iron. Energy loss in a transformer can be reduced by using thinner laminations, very “soft” (low-carbon) iron and wire with a larger cros ...
