A ferromagnetic ring has a uniform cross-sectional area of 2000 mm² and a mean circumference of 1000 mm. A hysteresis loop obtained for the specimen is plotted to scales of 10 mm = 0.1 T and 10 mm = 400A/m and is found to have an area of 104 mm². Determine the hysteresis loss at a frequency of 80 Hz.

What are the conditions to be satisfied in Gaussian surface?

3. In a coaxial cable having a conducting core and a conducting jacket, which Bessel function could be used to describe the radial dependence of the guided fields? Give explanations for your answers.

Q1. a) (i) Describe in words how Gauss's law is applied to determine the free charge on an arbitrarily shaped metal surface. (ii) Describe the two most useful Gaussian surfaces. Where are they used and what differences must be accounted for when applying them?

1) A permeant dipole moment p moves with a constant velocity vin +x direction. Let o be the shortest vector drawn from a point charge +0 on the -y axis to the path of the particle. The direction of p is given by Tv. v To Q Path of Particle a) Find the magnitude and direction of the torque on the dipole when it is at a distance r from the point charge + at time t. b) Assume that the particle moves so fast that the orientation of the dipole does not change while the particle is near the point charge +Q. Which component of the angular momentum L changes along V. c) Find the change in this component of the angular momentum along
