Hi,(adsbygoogle = window.adsbygoogle || []).push({});

My Question:

A 22.0 cm- diameter coil consists of 20 turns of circular copper wire 2.6 mm in diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 8.65 x 10^-3 T/S.

Determine the rate of which thermal energy is produced.

My work:

P= i^2 x R

P= (.0013 A)^2(6.96 x 10^-4 ohms)

P= 1.18 x 10^-19 W

After this I'm lost. Should I look into trying to incorporate the rate, so that I can find the rate of which thermal energy is produced

Thank You
