This course provides an overview of the way in which field theory pervades the discipline of physics. Special reference is made to gravitational fields and forces, gravitational potential, satellite motion, simple electrostatic phenomena, electric fields and forces, electric potential, magnetic flux and magnetic flux density, magnetic force on a current carrying conductor, magnetic force on a moving charge, magnetic fields due to currents in wires, coils and solenoids, laws of electromagnetic induction, and applications of electromagnetic induction.
