Electrodynamics Flashcards
1
Q
Magnetic flux linkage
A
The product of the number of turns on the coil and the flux through the coil (λ=Nφ)
2
Q
Faradays law
A
The emf induced is directly proportional to the rate of change of magnetic flux (flux linkage)
(EMF= -N(φ/t) )
3
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
4
Q
Diode
A
A component that only allows current to flow in one direction
5
Q
Μagnetic flux
A
Product of area of the coil and magnetic flux density [φ=BAcosθ]
