ANNEXURE C: TENDER - BASIC PHASE TRAINING EQUIPMENT 1) ELECTROLAB700 THE BACK TO BASICS TRAINER The basic trainer needs to have multifunctional choice of components: E.g. The electromagnet must be able to be used to demonstrate Electromagnetism, Transformer action, Lenz’s Law, Motor action etc. It needs to have five meters instead of single multimeter, a galvanometer that can shows what happens when a magnet moves inside a coil and if you heat the thermocouple that current flow can be noted.
