Magnetic Fields and Forces
- Magnetism is very similar to electricity -- in fact, they are really
two manifestations of the same physical phenomenon
- Magnetic poles --- north and south --- are analogous to electric
charges --- positive and negative --- with the exception that
one cannot isolate a single magnetic pole
- Magnetic fields do not affect uncharged particles
- Magnetic fields do not affect charged particles at rest, but they
do alter the direction of charged particles in motion
- The magnetic force on a particle of charge q moving
with velocity v in a magnetic field B is given
by the cross product
F = q (v x B)
- The SI units of magnetic field are Tesla = newton / (amp-meter)
