Given,
Galvanometer Resistance, RG = 75 Ω.
Current on galvanometer, ig= 5 mA
Range of current, = 0 to 5 A
We know,
(i) What is meant by a paramagnetic substance? State Curie’s law.
(ii) What is the value of magnetic susceptibility of Aluminium of its relative permeability is 1.000022?
How much force per unit length acts on a long current carrying conductor X due to a current flowing through another similar conductor Y, kept parallel to it in vacuum ?
Use this equation to define an Ampere, the fundamental unit of current.
(i) Arrange all the seven types of electro-magnetic radiations in increasing order of their frequencies. (You must begin with a radiation with lowest frequency and end with the one having the highest frequency.)
(ii) State how electric vector E, magnetic vector B and velocity vector C are oriented in an electromagnetic wave.
