electromagnetism Flashcards
1
Q
Magnetic Field definition
electromagnetism
A
a region of space where a force acts on a magnet / moving charge / current-carrying conductor
2
Q
Magnetic Flux Density definition
electromagnetism
A
magnetic force per unit current per unit length acting on a current-carrying long straight conductor placed perpendicular to the magnetic field
3
Q
Faraday’s Law
electromagnetism
A
the magnitude of the induced e.m.f in a conductor is directly proportional to the rate of change of magnetic flux linkage (or the rate of cutting of flux)
4
Q
Lenz Law definition
electromagnetism
A
the direction of the induced e.m.f is such that it produces effects that oppose the change that causes it
