1
Q
Faradays law
A
The emf induced is directly proportional to the rate of change of magnetic flux
2
Q
AC
A
Alternating current. Current which reverses direction periodically.
3
Q
Faradays law
A
The emf induced is directly proportional to the rate of change of magnetic flux
4
Q
DC
A
Direct current. Current flowing in one direction only.
5
Q
Lenz 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
Magnetic fields
A
Produced by magnets or by moving electrical charges. Magnetic field lines are drawn to represent the direction of the magnetic field at a point. The
symbol for magnetic field is B and its unit is the Tesla (T).
