(a) A circular coil of radius 1cm has 200 turns. It is removed from a magnetic field of 2T in a time of 0.1s. The field direction is normal to the plane of the coil. i. What is the magnitude of the average voltage induced in the coil? ii. If the coil is removed more slowly in a time of 1s, what is the magnitude of the voltage induced now? (b) A conductor located at x = 0.5 m, y = 0 and 0 < z < 2.0 m carries a current of 6.0 A in the direction along the length of the conductor B=2.5a, T. Find the torque about the z axis. (c) The equation for the induced field can be written as E =uXB, where E is the induced field, u is the velocity and B is the magnetic field. State the two conditions needed for the field to be induced. Explain briefly what Maxwell's equations are used for. Give four applications of electromagnetic fields. Maxwell's equation for Gauss' law for electric fields is given by VD=p... Light is a form of electromagnetic waves and it also consists of photon particles, where they are no free charges. Demonstrate how this equation can be rewritten to reflect a situation where there are no charges. (d) (e) (f)
