Question

A magnet falls with its S-pole along the axis of a ring. The current generated is ................ and acceleration is .................

• A. clockwise, $>g$
• B. clockwise, $<g$
• C. anti-clockwise, $>g$
• D. anti-clockwise, $<g$
• E. clockwise, $=g$

Answer 1

The correct option is B clockwise, $<g$

According to Lenz law, south poll should generate so that it can repel the bar magnet. Therefore current in the ring will be clockwise and hence $a<g.$
