Magnetism review sheet Flashcards
Magnetic field?
distribution of flux lines around a magnet
Flux density?
quantity of flux lines per unit area
Magnetic poles?
Distinct region where flux lines concentrate (exit and enter)
Laws of Attraction and Repulsion?
like magnetic poles repel and unlike poles attract
Ferromagnetic materials?
substances which exhibit the same magnetic properties as iron
Electromagnetism?
Establishment of flux lines resulting from current
a magnetic field surrounding a conductor/coil?
quantity and direction of flux lines is a result of the magnitude and direction of current flow
Magnemotive force?
Strength which produces electromagnetism
reluctance?
opposition to flux lines
Permeability?
ease of setting up flux lines
B-H curve?
graph which illustrates relationship of flux density and magnetizing force
Saturation?
max level of flux density
