 The figure above shows a flexible wire loop lying on a frictionless table top. The wire can slide around and change its shape freely, but it cannot move perpendicular to the table. Part a:
If a current were made to flow counterclockwise in the loop which of the following would happen? - The wire would stretch out into a circle
- The wire would contract down to a tangled mess
- Nothing
- There is not enough information to tell.
Part b:
If the current went clockwise, would that affect your answer to part a? Please answer this in words, not equations, briefly explaining how you obtained your answer.
