question 114

Multiple Choice

Coil $\mathrm { A }$ is close to, but not touching, coil B. If a steady counterclockwise $100 - \mathrm { A }$ current flows in coil A, what can you say about the induced current in coil B?

• A) The current in coil B will be clockwise and less than \(100 \mathrm {~A}\), but not zero.
• B) The current in coil \(\mathrm { B }\) will be equal to \(100 \mathrm {~A}\) counterclockwise.
• C) The current in coil B will be counterclockwise and less than \(100 \mathrm {~A}\), but not zero.
• D) There will be no induced current in coil B.
• E) The current in coil B will be equal to 100 A clockwise.
