The Figure Shows Three Metal Coils Labeled A, B, and C

question 65

Multiple Choice

The figure shows three metal coils labeled A, B, and C heading towards a region where a uniform static magnetic field exists. The coils move with the same constant velocity and all have the same resistance. Their relative sizes are indicated by the background grid. As they enter the magnetic field the coils will have an induced electric current in them. For which coil will the current be the greatest?

• A) A
• B) B
• C) C
• D) The current is the same in all three cases since all the coils move with the same velocity.
• E) There is no induced current in any of the coils since they move at constant velocity.
