Magnetism and Moving charges
*Oersted had showed in the 19th century that a current carrying conductor was surrounded by a magnetic field
*Moving charges experience a force in a magnetic field
Factors that effect the magnitude of force
*F = ILBsinƒÖ
Van Allen Radiation belts - example pf motion of charged particles in a field
*Charged particles trapped inside the earth's magnetic field, which oscillate back and forth between the poles
*These charged particles experience a force due to earth's magnetic field
