... A current balance is an instrument used to demonstrate the deflecting force of a current carrying wire in an external magnetic field. The current balance is constructed of a small rectangular piece of wood with a piece of wire around half of the perimeter of the wood (WXYZ in the diagram below). The ...

How can two distant objects exert a force on each other when they are so very far from touching? “Hypotheses non fingo,” said Newton, which has been translated as, “I frame no hypotheses.” A different person, with today’s sensibilities, might have said, “Look you fool ...

... semiconductors. All these electrons can respond to a (changing) magnetic field. Here we will only look at the (much simplified) case of a bound electron orbiting a nucleus in a circular orbit. The basic response of an orbiting electron to a changing magnetic field is a precession of the orbit, i.e. ...
