1
Q
Describe Hall Voltage
A
2
Q
Determining Hall Voltage
A
F = Bqv
F = Eq
E = Vh / d
Bvd = Vh
3
Q
Fleming’s LHR
A
Current represents the motion of a positively charged particle (velocity parallel)
4
Q
Describe Faraday’s Law
A
When magnetic field lines are cut, flux is changing. Due to Faraday’s Law, emf is directly proportional to the negative rate of change of flux linkage wrt time, so electromotive force is induced.
