A long, cylindrical rod of radius a carries a uniformly distributed free current I. The rod is made of a paramagnetic material, which has a relative magnetic permeability µr slightly greater than 1. The resistance per unit length of this wire is R. Figure 2 (a) For the regions inside and outside the rod, find the a. magnetic field strength H, b. magnetic flux density B, c. magnetization M. (b) Write down Poynting’s theorem in words, and also in equation form. (Derivation is not needed, but you should explain each of the symbols used.) (c) By integration of the Poynting vector, show that the power flow per unit length into the wire from the Poynting vector is equal to the ohmic power dissipated per unit length in the wire.

As shown in Figure 3(a), a wooden block B with mass mB = 2.4 kg on a rough inclined plane is connected to a massless spring ( k = 160 N/m ) by a massless cord passing over a pulley P of radius R = 0.25 m and mass Mp = 0.60 kg. The angle of the inclined plane is θ = 37∘ and the coefficients of static and kinetic frictions are μs = 0.35 and μk = 0.30 respectively. The frictional force at the axle of the pulley is negligible. The pulley can be regarded as a solid disk. (a) The system is at rest and in this case, block B is on the verge of sliding down. Figure 3(a) i. Indicate (with labeled arrows) the forces acting on the pulley and the block. ii. Calculate the tension in the string and the extension of the spring. (You can assume that the tensions in the cord on either side of the pulley P are the same for this part.) (b) As shown in Figure 3(b), another wooden block A of mass mA = 1.2 kg made of the same material as block B is released from rest. It slides down a distance l down the rough inclined plane and collides with block B. The two blocks stick together and move down the incline with a common velocity v = 0.80 m/s immediately after collision and the pulley rotates. The cord does not stretch and does not slip on the pulley. Figure 3(b) i. Determine the distance l. ii. Determine the acceleration of the two blocks at the moment they move down together and the pulley starts to rotate. iii. Determine how much further down the slope the two blocks move together after they collide before the two blocks come to a momentary rest.

A ductile metal wire has resistance R. Part A What will be the resistance of this wire in terms of R if it is stretched to three times its original length, assuming that the density and resistivity of the material do not change when the wire is stretched. (Hint: The amount of metal does not change, so stretching out the wire will affect its cross-sectional area. ) Express your answer in terms of R.R′ = R
