DC generator 

A DC generator operates on the principle of Faraday's laws of electromagnetic induction. According to Faraday's law, whenever a conductor is placed in a fluctuating magnetic field (or when a conductor is moved in a magnetic field) an EMF is induced in the conductor

Question after understand the emf equation

Q1

The armature of an 8- pole DC generator has 960 conductors and runs at 400 RPM the flux per Pole is 40 Mili Weber (i) calculate the induced EMF, if the armature is lap-wound (ii) at what speed should it be driven to generate 400 volt if the armature were wave connected ?

COPPER & IRON LOSSES IN A TRANSFORMER 

1. These losses occur in the core of the transformer and are generated due to the variations in the flux.  They depend upon the magnetic properties of the material used for the construction of core. Hence these losses are also known as core losses or iron losses (Wi).

hysteresis loss vs eddy current

The most significant difference between the Eddy current and Hysteresis loss is that the eddy current loss occurs because of the relative motion between the conductor and the magnetic field. Whereas the hysteresis loss occurs because of the reversal of the magnetism
