Magnetic Fields Flashcards
1
Q
Define magnetic flux
A
Magnetic flux density X area normal to the field
2
Q
Define magnetic flux linkage
A
Magnetic flux passing through a coil
3
Q
State Faraday’s Law
A
Induced e.m.f is directly proportional to the rate of change of magnetic flux linkage
4
Q
State Lenz’s law
A
The direction of the induced e.m.f opposes the change producing it.
5
Q
Define magnetic flux density
A
B = F / IL
Amount of magnetic flux passes through an area
