Chapter Overview
Chapter 19, 'Electromagnetism', explores the relationship between electricity and magnetism. It begins with the magnetic field created by current-carrying straight wires and solenoids, using right-hand rules to find field direction, and introduces Earth's magnetic field. Students analyze the force exerted on a current-carrying conductor in an external magnetic field.
The working principles of electric motors are investigated, showing how a current loop experiences torque in a magnetic field. It then introduces electromagnetic induction, outlining Faraday's Law and Lenz's Law for induced EMF. These principles lead to the operation of electric generators and transformers (step-up and step-down).
Finally, the chapter covers electron dynamics in magnetic fields, illustrating electron beam deflection. This is applied to study the construction and operation of the Cathode Ray Oscilloscope (CRO) as an analytical tool. This integrates classical electromagnetism with introductory electronics.
