a)Oersted experiment predicts that elecetric current produces a magnetic field. faraday found from his experiment that a changing magnetic field produces an electric field. is the reverse true can a changing melectric field produces a magnetic field this answer is given by clerk maxwell. He states that magnetic field not only proces by electric current but also by a time varying electric field.He also pointed out that ampere's circuital law becomes consistent only if along with conduction current, there is an additional current called by him th displacement current.

4. The enthalpy H may be written as a function of temperature T and pressure P. If we have a system whose composition remains constant and using Maxwell's equations and the total differential, we can write dH as avdP where Cp is the heat capacity at constant pressure and the subscript of P on the partial derivative represents the partial of volume with respect to temperature holding pressure connstant. Find the change in enthalpy (A) for an ideal gas undergoing...

Question 1. (a) Write down the differential form of Maxwell's equations in matter for the dynamic case (where the electric and magnetic field can change with time), in the presence of free charges and currents. Describe all physical quantities and constants used. [10] (6) (b) Write down the integral form of Ampere's law in vacuum for the static (non time- dependent) case. Using Stokes' theorem, derive the differential form of Ampere's law. [4] (c) Two charges 91= 5 uC and...

E16D.1 Consider a circular loop of radius R that is expand- ing at a rate of dR/dt in a static and uniform magnetic field B that is perpendicular to the loop's face. Since the mag- netic field is static and uniform in every frame of reference, Faraday's law ХЕ + дв/at 0 tells us that the electric field in any frame in this situation must have zero curl and therefore cannot drive a current around the loop. (a) At a...
