A 19.0-cm -diameter coil consists of 40 turns of circular copper wire 2.8 mm in diameter. A uniform magnetic field, perpendicular to the plane of the coil, changes at a rate of 8.10×10−3 T/s . The resistivity of copper is 1.68×10−8Ω⋅m .

Part A) Determine the current in the loop

Part B) Determine the rate at which thermal energy is produced

The resistivity of copper at 25°C is ρ = 1.68×10^-8 Ω.mThe length of the copper wire isL = N (πD) = 40π×19 cm =760 π cm = 7.6 π metersThe sectional area of the wire isA = π d²/4 =...
