The figure below shows a flexible loop of metal wire with a radius of 10.0 cm. It lies in a magnetic field pointing into the page with a magnitude of 0.130 T. An engineer grabs the loop at points A and B and rapidly pulls in opposite directions until the loop folds up, such that its area becomes zero. The change in area occurs in a span of 0.250 s. A В What is the average induced emf (in mV) in the loop over this time span? 16 What is the initial magnetic flux through the loop? If the loop's area goes to zero, what is the final flux? How is the change in flux and change in time related to the induced emf? Be careful with unit conversions. mV

Suppose a magnetic field B(t) oscillates with frequency w. A circular loop of copper lies perpendicular to the magnetic field. The radius of the circular loop is r. a. Write down an expression for the magnetic field as a function of time. Determine the induced emf & in the loop of wire and use this to calculate the current generated in the loop as a function of time. b. What is the power dissipation in the wire as a function to time? Make a sketch of this function. What is the average power Pave dissipation in the wire? Hint: what is the average value of the function you sketched? C. Recall that power is a rate of energy transfer, and that power dissipated by a resistor leads to a change in the thermal energy of the material (in this case the copper wire). We can relate a change in thermal energy to a change in temperature by AT where M is the total mass and c ΔΕth Mc is the specific heat capacity of the material (see page 526 for details).
