PLAN1. Crossed fields: the Hall effect2. Circular and helical motions of a charged particle in a magnetic fieldMagnetic field does no work on a chargedparticle.3. Magnetic force on a current-carrying wire4. Magnetic dipole momentMagnetic field DOES work on a magneticdipole moment.Helical motion of charged particles in magnetic fieldWhy does a charged particle get trapped by the planet?Magnetic Dipole MomentMagnetic dipole momentExamples: Current carrying coil: μ= N i A (definition of the magnitude) Bar magnet Magnetic ions making up bar magnets and other magnetic materials.Vector:Counterclockwise i up (right-hand definition). Electric dipole momentµvμ= i Ap = q
