1
Q
weber
A
One weber is the amount of magnetic flux that when reduced to zero in one second induces an e.m.f of one volt
1Wb=1V x 1s
2
Q
Magnetic flux linkage
A
The magnetic flux linkage through a loop is the product of the magnetic flux through the loop and the number of turns of wire in the loop
3
Q
Faradays law
A
Faraday’s Law states that the magnitude of the e.m.f induced is proportional to rate of change of magnetic flux linkage
4
Q
Lenz’s law
A
Lenz’s law states that an e.m.f. is induced in the direction such as to oppose the change in the flux linkage that is inducing it
