Question

For a triangular loop leaving an out-of-page magnetic field, what is the induced current direction and path?

Options

• Anticlockwise, along \[b\rightarrow a\rightarrow c\rightarrow b\]

• Clockwise, along \[b\rightarrow c\rightarrow d\rightarrow a\rightarrow b\]

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

• No current flows while the loop leaves the field.

Answer 1

The induced field must point out of the page to oppose decreasing flux. The Right-Hand Thumb Rule gives an anticlockwise current along \[b\rightarrow a\rightarrow c\rightarrow b\].
