5.5 Magnetic Fields Flashcards
1
Q
Magnetic flux density, B
A
The force per unit current currying length
2
Q
Tesla
A
One tesla is the magnetic flux density which will cause a conductor 1m long, carrying a current of 1A, at right angles to the fieldI to experience a force of 1N
3
Q
Faradays law
A
Induced EMF is directly proportional to the rate of change of flux linkage
4
Q
Lenz’s law
A
The direction of the induced current is such that it opposes the change in magnetic flux that is producing it
