ELECTRO MAGNETISM:
In this unit we learned about electromagnetism and the relationship that presents between and magnetic flux and electric current. The way in which electric current magnetizes a magnetic material was discussed in magnetization curve or B-H curve. In relation to B-H curve, phenomenon of magnetic hysteresis was also explained.
Magnetic circuit provides a path for magnetic flux and this is the basis of electromagnetism. Types of magnetic circuits which can be series or parallel were discussed.
A current carrying coil has self inductance and the inductance among two coils is called mutual inductance. We had elaborate discussion on these with instance. The coefficient of coupling among two coils find the degree of linking between their fluxes and it was studied.
Dot convention finds out whether e.m.fs between two mutually coupled coils are aiding or opposing and this was depicted with examples.
Series or parallel connection among two current carrying coils was explained. Series and parallel connection can again be aiding or opposing.
Q. A beam containing two types of charged particles is moving from A to B. Particles of type I with charge +3q, and those of type II with charge -2q (where -q is the charge of an e
