Electrodynamics Flashcards
1
Q
What is Magnetic Flux density?
A
Magnetic flux density is a representation of the magnitude and direction of the magnetic field .
2
Q
What is Magnetic Flux Linkage?
A
Magnetic Flux linkage is the product of the number of turns on the coal and the flux through the coil.
3
Q
What does Faraday’s law state?
A
The emf induced is directly proportional to the rate of change of magnetic flux.
4
Q
What does Lenz’s law state?
A
The induced current flows in a direction so as to set up a magnetic field to oppose the change in magnetic flux.
5
Q
What is a diode?
A
A component that only allows current to flow in one direction.
