Magnitism Flashcards
1
Q
Mutual inductance
A
The changing current in the primary coil creates a changing magnetic flux through the secondary coil, which leads to an induced emf in the secondary coil.
2
Q
Self inductance
A
The effect in which a changing current in a circuit induces an emf in the same circuit
3
Q
Transformers
A
A device for increasing or decreasing an ac voltage.
4
Q
Magnetic flux
A
The number of field lines passing through a surface.
