Overview
Students should be able to identify the directions of current, magnetic field. Explain the action of a loop wire carrying current in a magnetic field Explain the basic working principle of the galvanometer and the electric motor. State and explain the implications of Lenz's law Explain how the conversation principle is involved in both laws with regard to : - Charge - energy State and explain Faraday's law of electromagnetic induction. explain the principle underlying the production of direct and alternating current State the use of induction coils and transformers. Explain the cores of the induction coil and the transformer are laminated
