Electrodynamics Flashcards
1
Q
Magnetic fluxes density (B)
A
A representation of the magnitude and direction of the magnetic field.
2
Q
Magnetic flux (Ø)
A
Passing through a loop is defined as Ø = BAcos* where * is the angle between the magnetic flux density (B) and the normal to the loop of the area (A)
3
Q
Magnetic flux linkage
A
The product of the number of turns on the coil and the flux through the coil (NØ)
4
Q
Faraday’s Law of electro magnetic induction
A
The emf induce is directly proportional to the rate of change of magnetic flux (Flux linkage)
5
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.
6
Q
Diode
A
A component that only allows current to flow in one direction.
