Question

Homework 11 Item 8 Correct A circular wire loop 43 cm in diameter has resistance 120 2 and lies in a horizontal plane. A uniform magnetic field points vertically downward, and in 25 ms it increases linearly from 5.0 mT to 55 mT. Part C What's the loop current during this time? Express your answer with the appropriate units. I- 2.4 Units Submit XIncorrect; Try Again; 4 attempts remaining Part D Which way does this current flow? Select the correct answer and explanation I is counterclockwise when viewed from above the loop because induced fi

Explanation / Answer

Magnetic flux=BA=B?r2 .

Induced emf=?r2(dB/dt)

=?(43/2)2×10- 4×5/25=2904.4×10-4V.

Current=emf/R=2904.4×10-4/120=2.42mA
