About this document
Electromagnetism and Induction Principles by Tesfahun Tegegne is a document available to read on EtoBox.
1. Electromagnetism is magnetism produced by electric current flowing through a conductor. The magnetic field produced has circular lines of force around the conductor. 2. Electromagnetic induction produces an induced electromotive force (emf) when there is relative motion between a conductor and a magnetic field or when the magnetic field changes. This can be generated using a coil and magnet or in a generator. 3. The direction of the induced emf depends on the direction of motion and magnetic field based
