6. Magnetic Forces and Materials

• Lorentz force law.
• Force on a current-carrying conductor.
• Torque on a current loop (electric motor principle).
• Magnetization, permeability, hysteresis – qualitative and quantitative.

5. Magnetostatics

Moving charges produce magnetic fields. Seth covers: A Comprehensive Resource: Electromagnetic Field Theory by S

• Biot-Savart law – applications to circular loops, solenoids.
• Ampere’s circuital law – integral and differential forms.
• Magnetic vector potential A.
• Boundary conditions for B and H.

Pay special attention to the magnetic scalar potential – a concept often tested in interviews. Lorentz force law

Q2: Which edition should I look for?

A: Latest is ~2016 (Romesh Publications or S. Chand). Older editions (2002–2008) are fine – Maxwell’s equations haven’t changed.
