Question

blackboard.uncp.edu Figure 6 2 of 4 6) A conducting carries a current /as shown in Figure 6. The current is increasing with time at a 6) constant rate. Which of the following is correct concerning the nature of the induced emf in each of the loops, A,B, and C? A) no emf is induced in any loop. B) all loops experience counterclockwise emf. C) loop A has counterclockwise emf, loop B has no induced emf, and loop C has clockwise emf. D) loop A has counterclockwise emf loop B clockwise emf, and loop C has clockwise emf. E) loop A has clockwise emf, loop B has no induced emf, and loop C has counterclockwise emf

Explanation / Answer

All loops experience counter clock wise emf.

The magnetic field lines passes through A out of the page accrding to lenzs law to oppose the magnetic field produced by induced current must into the page for this emf must in counter clock wise direction . similarly remaining.
