Topics in Moving Charges and Magnetism
1
4.1 Introduction and Basic Concepts
- Oersted's experiment (1820) showed that electric current produces magnetic field
- Current emerging from paper: ⊙, Current going into paper: ⊗
- Unification of electricity and magnetism by James Maxwell (1864)
2
4.2 Magnetic Force on Moving Charges
- Lorentz force law combines electric and magnetic forces
- Magnetic force is always perpendicular to both velocity and magnetic field
- No magnetic force on stationary charges
3
4.3 Motion of Charged Particles in Magnetic Field
- Three cases: v ∥ B (straight line), v ⟂ B (circular), v at angle (helical)
- Circular motion: magnetic force provides centripetal force
- Time period independent of speed and radius
4
4.4 Biot-Savart Law
- Gives magnetic field due to current element
- Similar to Coulomb's law but with vector source and different geometry
- Field perpendicular to plane containing current element and position vector
