Chapter 3
Steady Magnetic Fields
Steady magnetic fields are produced by steady currents.
The main objective of this chapter is to provide detailed concepts of magnetostatics. They include:
- applications of magnetostatic fields
- Faraday’s induction law, Biot-Savart law, Ampere’s circuit law, Ampere’s force laws for current elements
- force on current element and between current elements Lorentz force equation
- Boundary conditions, scalar and vector magnetic potentials
- fields in magnetic materials
- inductances
- energy stored in magnetic field and inductors
- comparison between electric and magnetic parameters/circuits
- points/formulae to remember, objective and multiple choice questions and exercise problems.
