... A square loop of wire of side l = 5.0 cm is in a uniform magnetic field B = 0.16 T. What is the B is magnetic flux in the loop (a) when B perpendicular to the face of the loop and (b) when B is at an angle of 30°to the area A A of the loop? (c) What is the magnitude of the average current in the loo ...

... At first sight a small resistance seems sensible, because then a large current will flow, but unfortunately drawing a large current from a supply lowers its voltage because of the supply’s internal resistance. In the extreme case of zero resistance, a very large current may flow, but all the power t ...

... From the definition of voltage as the energy per unit charge, one might expect that the energy stored on this ideal capacitor would be just QV. That is, all the work done on the charge in moving it from one plate to the other would appear as energy stored. But in fact, the expression above shows tha ...

... The expression one or more means exactly that, there may be 1, 2, 3 or 4 correct answers. If it does not say one or more then there is only one 'best' answer. If the wire is being pushed then F = nBIL, implies that n, B, I, L are all non-zero, they exist. Answer C is correct because it is actually ...

Few candidates stated that the wire would move along the copper wires to the right. In part (ii) many had the movement reversed, but reversing an up/down movement does not give a correct ...
