10 - electromagnetic induction Flashcards
1
Q
Magnetic flux (EMI)
A
Product of magnetic flux density normal to a circuit and the cross sectional area of the circuit.
2
Q
1 Weber
A
the flux that passes through an area of 1m2 when magnetic flux density is 1T
3
Q
Magnetic flux linkage
A
product of magnetic flux and number of turns
4
Q
Faraday’s law
A
The magnitude of induced EMF is proportional to the rate of change of magnetic flux linkage.
5
Q
Lenz’s law
A
the direction of induced EMF is such that it tends to oppose the change causing it.
