Electric and Magnetic Fields

Electric and Magnetic Fields

1. Capacitance

   • Diagram
   • Capacitor charging
   • Capacitor discharging
   • Derivation

2. Electric Fields

   • Electric potential
   • Field lines and equipotentials
     • Uniform
     • Radial
     • Electric fields have equipotential surfaces. The potential is the same everywhere. Therefore, when charge moves along the surface, no work is done.

3. Magnetic Fields

   • Current carrying conductors
   • Charged particles moving
   • Magnetic flux density, flux and magnetic flux linkage
   • e.m.f in coil
   • Lenz law
   • Faradays law
   • Alternating currents

4. Electromagnetic induction and alternating current
