Pre-Quantum Electrodynamics

Fundamentals: After properly studying this module, you should be able to:

• give the definition of magnetization
• explain the difference between paramagnets, diamagnets and ferromagnets
• state the formula for the torque on a magnetic dipole in a uniform field
• state the formula for bound volume current and bound surface current in terms of the magnetization
• give the definition of the \({\boldsymbol H}\) field
• state Ampère's law in terms of \({\boldsymbol H}\) (differential and integral forms)
• give the definition of susceptibility and permeability for linear media

Applications: As a strict minimum, you should be able to:

• compute \({\boldsymbol H}\) for simple geometries
