Question

What is the induced current path for an irregular loop moving out of an out-of-page magnetic field?

Options

• \[c\rightarrow d\rightarrow a\rightarrow b\rightarrow c\]

• \[b\rightarrow c\rightarrow d\rightarrow a\rightarrow b\]

• \[b\rightarrow a\rightarrow c\rightarrow b\]

• No current path is produced.

Answer 1

The induced current must produce an out-of-page field to oppose the decreasing flux. For the irregular loop, its path is \[c\rightarrow d\rightarrow a\rightarrow b\rightarrow c\].
