What is Eddy Current Dynamometer? Working, Diagram, Construction & Applications
Fig. 1: Eddy current dynamometer.
Working Principle of Eddy Current Dynamometer
Eddy current dynamometer is electrical absorption dynamometer working on principle that, when isolated conductor moves through magnetic flux, it induces eddy current, which get dissipated in the form of heat.
