State clearly the principle of Physics that you are using (invoking is the scientific word). Explain (briefly) your methodology. Give any equations that you may use, 1. A coil has 200 turns (loops) each loop has an area of 0.0324 m2. A uniform magnetic field is applied perpendicular to the plane of the coil. The field changes linearly from 0 to 0.50 Wb/m2 in a time of 0.8 s. Find the magnitude of the induced EMF (voltage) in the coil.

SECTION A You must answer ALL questions in this Section. 1. Explain (with specific reference to Maxwell's equations) why a traveling wave in the electric field must always be associated with a propagating wave in the magnetic field. 2. Explain why a free charge q will be attracted to the surface of an electrically neutral conductor, and explain how you expect this force to vary with distance compared to the regular Coulomb force between two charges. 3. Explain how you could estimate the refractive index of glass given a power supply, a sheet of glass, two flat pieces of metal, some wire and appropriate instruments for measuring the properties of electrical circuits. 4. With reference to one or more of Maxwell's equations, explain why it is apparently impossible to find a static magnetic field which has a "porcupine" configuration - that is, a surface at which all the field vectors are pointing in the outward direction. 5. Describe the phenomenon of diamagnetism. A grape (which consists…

L. B A positively charged particle is tied by a massless string and allowed to move on a smooth plane, as shown in the picture. A uniform magnetic field B = 1 T is applied perpendicular to the plane pointing down. The length of the string is L = 25 cm. The mass of the particle is m = 35 kg. The charge on this particle is q = 0.65 C. The velocity of the motion is a constant v = observing from above the plane.

A conducting rectangular loop of mass M, resistance R, and dimensions a x b is allowed to fall from rest through a uniform magnetic field which is perpendicular to the plane of the loop. The loop accelerates until it reaches a terminal speed (before the upper end enters the magnetic field). If a = 2.1 m, B = 3.8 T, R = 79 Ω, and M = 0.2 kg, what is the terminal speed? To continue please enter your result in units of m/s. Round your answer to 1 decimal place.

A Fig.1 A current i = –10 mAs flowing through the two infinitely long straight wire segments connected by a semi-circular arc, as depicted in the figure. The semi-circular arc has a radius R = 18 mmPoint A is equidistant from both the infinitely long straight wire segments and also very far away from the semi-circular arc. The coordinate directions are shown in the figure. Note: If the value of current given in the question is positive, then direction of current flow will be the same as depicted in the figure. For the negative value of current, the direction of current flow will be opposite to the direction shown in the figure. a) Find the magnetic field in unit vector notation at point A x component of the magnetic field Give your answer to at least three significance digits.
