Chapter 14 Electromagnetism includes topics:
- Electromagnetism
- Force on a current carrying coil in magnetic field
- Magnetic Flux and Magnetic Density
- Ampere’s law
- Determination of flux density
- Force on a moving charge in a magnetic field
- Lorentz Force
- Determination of e/m
- CRO – Cathode Ray Oscilloscope
- Torque on a current carrying coil
