Inductance and Inductors Flashcards
1
Q
What is Faraday law?
A
A voltage is induced across a conductor whenever relative motion exists between the conductor and a magnetic field. The induced voltage is directly proportional to either:
The rate of flux cut by a single wire.
The rate of change of flux passing through a coil of wire.
2
Q
What factors affect mutual inductance?
A
Increasing the number of turns on the coils and
Increasing the cross-sectional area of the coils
Decreasing the length of the coils
Increasing the permeability of the material used in the common core
