Construction of a Simple Transformer to Illustrate Faraday’s Law of Electromagnetic Induction along Side Mutual Inductance

Abstract

The concept of mutual induction which arises from Faraday’s law of electromagnetic induction is a major concerned about the size of the magnetic flux cutting across a wire which is directly proportional to the induced Electromotive Force (e.m.f.), this is often time being thought without reference to a physical device. The methodology employed includes the construction and testing of a simple device called transformer. This device is made up of copper wire, thin insulated iron, output display meter, switch, fuse, simple handle and structural wooden case. With this device, an experiment is conducted to illustrate Faraday’s law of electromagnetism. This work presents a suitable reproducible device for illustrating mutual induction of a coil. Using an analytical approach, the result obtained signified a step-down transformer. Base on the output result, the transformer can function effectively to give a low voltage output to electrical gadgets.
