A Flexible,circular Conducting Loop of Radius 0

question 71

Multiple Choice

A flexible,circular conducting loop of radius 0.15 m and resistance 4.0 lies in a uniform magnetic field of 0.25 T.The loop is pulled on opposite sides by equal forces and stretched until its enclosed area is essentially zero m²,as suggested in the drawings.It takes 0.30 s to close the loop.

-Which one of the following phrases best describes the direction of the induced magnetic field generated by the current induced in the loop while the loop is being stretched?

• A)clockwise
• B)counterclockwise
• C)into the page
• D)out of the page
• E)The induced field is zero.
