EEN 1042 Physical Electronics
... The simple quantitative results given below are in only fair agreement with experiment. In particular, the Hall coefficient does depend on the strength of the magnetic field at large fields, and at small fields its value differs from those quoted above by factors that depend on the specific kinds of ...

... that the outside magnetic field itself rotates. The inner coils around the central rotor of the motor are not connected to a current source. Instead, a current is induced in them by the magnetic field of the stator, and this induced current creates the inner magnetic field that attempts to align its ...

The electric potential
... Equipotential surfaces and the potential gradient. An equivalent form of the second law of electrostatics As it was already pointed out at the beginning of this lecture the electric field strength is the negative gradient of the electric potential: E = - grad. Now we are going to prove this importa ...
