Electrodynamics Flashcards
1
Q
Magnetic flux density (B)
A
A representation of the magnitude and direction of the magnetic field
2
Q
Magnetic flux linkage
A
The product of the number of turns on the coil and the flux through the coil (Nø)
3
Q
Faraday’s law of electromagnetic induction
A
The emf induced is directly proportional to the rate of change of magnetic flux (flux linkage)
4
Q
Lenz’s law
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
Diode
A
A component that only allows current to flow in one direction
