is the amount of magnetic flux linked with one coil when a current I flow through the other coil, then f = MI , where M is coefficient of mutual induction of two coils. Hence coefficient of mutual induction of two coils is equal to the EMF induced in one coil, when rate of change of current..

Coulomb's Law - It states that "the electrostatic force between two electric charges is directly proportional to the product of the charges and inversely proportional to the square of the distance between them ..

Pierre Curie experimentally discovered that intensity of magnetization I is directly proportional to B o (flux density in Vacuum) and inversely proportional to the absolute temperature. T of the material That is I a B o /T or I=c B o /T Here, C is Curies constant. The saturation region explains tha..

Laws of Radioactive Disintegration - The number of atoms disintegrated per second at any instant is directly proportional to the number of radioactive atoms actually present in the sample at that instant. If N o be the total number of atoms at t = 0, N be the total number of atoms left in..

Biot and Savart's Law - The Biot - Savart's law enables us to write the general results for the magnetic field due to an arbitrary current distribution or it is an experimental law predicted by Biot and Savart dealing with magnetic field strength at a point due to a sm..

the field at all points on the circle and the direction is given by the tangent drawn to the circle at that point. i.e., the flux is equal to the times the current threading through the area bounded by the circle. Hence, Ampere circuital law can be stated as follows "The line integra..
