Electromagnetic Induction Definitions Flashcards
1
Q
magnetic flux density (B)
A
a representation of the magnitude and direction of the magnetic field (magnetic field strength)
2
Q
magnetic flux linkage
A
the product of the number of turns in the coil and flux through the coil
3
Q
Faraday’s Law of electromagnetic induction
A
the emf induced is directly proportional to the rate of change of magnetic flux linkage
4
Q
Lenz’s Law
A
the induced current flows in a direction as to set up a magnetic field to oppose the change in magnetic flux
5
Q
diode
A
component that only allows current to flow in one direction
6
Q
magnetic flux
A
total number of field lines through an area
