Suppose you wish to measure the current in a wire. You have a device that can measure the strength of the magnetic field produced by the wire, but the device does not directly measure the current. If the device is place 0.98m away from the wire, and the magnetic field strength is 1.72µT, what is the current running through the wire in Amps? Note: It is understood that the unit of your answer is in A, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit, your answer will be counted wrong.

A circular closed, conducting loop of radius r is in the presence of a uniform magnetic field that points into the page, shown in the figure below. The strength of the magnetic field changes as a function of time, which is described by the following expression: B(t) = B1t? + Bo. You may assume that B1 and Bo are both positive numbers. The direction of the magnetic field stays constant. The total resistance of the conducting loop is R. Use this information to solve parts (a) - (d). Write your answers in terms of known quantities such as: r, R, B1, Bo, and t.
