Current Attempt in Progress Your answer is partially correct. If 52.3 cm of copper wire (diameter = 1.26 mm, resistivity = $1.69 \times 10^{-8} \Omega \cdot m$) is formed into a circular loop and placed perpendicular to a uniform magnetic field that is increasing at the constant rate of 10.6 mT/s, at what rate is thermal energy generated in the loop?

Step 1
The length of the wire is $L = 52.3 \, cm = 0.523 \, m$. The circumference of the circle is $C = 2\pi r = L$, so the radius is $r = \frac{L}{2\pi} = \frac{0.523}{2\pi} \approx 0.0832 \, m$. Show more…

A 43.6 cm length of wire, when used as a resistor, has a resistance of 0.00594 Ω. The ends of the wire are connected to form a circular loop, and the plane of the loop is positioned at right angles to a uniform magnetic field that is increasing at the rate of 0.0551 T/s. At what rate is thermal energy generated in the wire? Answer in units of µW.
