You know that Ampere's circuital law is mathematically expressed as given below.
` oint vecB vec( dt) - mu _0 I `
Also you know that this law was corrected by Maxwell and which is known as Ampere-Maxwell law. Write the general form of the law and name the additional term.

Maxwell's modified form of Ampere's circuital law is

Ampere's law provides us an easy way to calculate the magnetic field due to a symmetrical distribution of current. Its mathemfield expression is ointvecB.dl=mu_0I_("in") . The quantity on the left hand side is known as line as integral of magnetic field over a closed Ampere's loop. In the above question, find the magnetic field induction at a point distance r from the axis when rgta. Assume relative permeability of the medium surrounding the conductor to be unity.

The quantity on the left hand side is known as line as integral of magnetic field over a closed Ampere's loop. If the current density in a linear conductor of radius a varies with r according to relation J=kr^2 , where k is a constant and r is the distance of a point from the axis of conductor, find the magnetic field induction at a point distance r from the axis when rlta. Assume relative permeability of the conductor to be unity.

We know that gases which donot react chemically intermix irrepective of their nature. This is known as diffusion. The law of gravitation does not apply to diffusion which means that lighter gases can more downward while the hevier ones can move upwards. (i) State Graham's Law of diffusion. (ii)Give Its mathemartical form. (iii) What is the value associated with the phenomenon of diffusion of gases?
