... Magnetism is the force of attraction or repulsion between a magnet and something else. Magnets attract materials made of iron, nickel, or cobalt. Can you think of five things to which a magnet may be attracted? Does it matter which end of the magnet is brought near the object All magnets, no matter ...

... Vp / np = Vs / ns h) If transformers are assumed to be 100% efficient,the electrical power output would equal the electrical power input. Vp x Ip = Vs x Is i) Switch mode transformers operate at a high frequency, often between 50 kHz and 200 kHz. j) Switch mode transformers are much lighter and smal ...

... These are the Maxwell equations for statics. The flux relations show that the electrostatic field has nonzero flux for a Gaussian surface enclosing charge because charges are sources and sinks of the electric field, whereas the magnetic field has zero flux out of a Gaussian surface because there are ...
