From Physics 212, one might get the impression that going... vacuum to electrostatics in a material is equivalent to replacing...
... proportionality constant given by the product of the electric susceptibility chi and epsilon_0. Since the electric field is constant, its divergence is zero and hence there is no bound charge volume density – all the bound charge must be on the dielectric surface. In this case it has a surface densi ...

... 1. The ends need more scraping – enamel is insulating the wire ends and current is not flowing through the coil. 2. The coil windings are not all going the same direction. 3. The wire is broken somewhere so current is not flowing in the coil. 4. The windings are shorting out because non insulating w ...

... In the 1200s, sailors learned how to make a compass that could help them find their way at sea. They made a needle from a thin piece of lodestone or iron. They hung the needle from a string. The needle always pointed north. Because Earth is a big magnet, the south pole of the compass needle always p ...
