held but untouched.: Magnetism Summary →
freshielle:
Magnetic field lines point from N to S.
The SI unit of the magnetic field is the Tesla: 1 T = 1 (N · s)/(m · C). When Tesla is too large, gauss is used: 1 Gause = 10e-4 Tesla.
The permeability of free space µ_0 is: µ_0 = 4π x 10e-7 N / A^2, which will be given on Test Day if needed.
