As Shown Below,a Square Loop of Wire of Side a Moves

question 8

Multiple Choice

As shown below,a square loop of wire of side a moves through a uniform magnetic field of magnitude B perpendicular to the page at constant velocity $\overrightarrow { \mathbf { v } }$ directed to the right.Which statement regarding the electric field induced in the wires is correct for the wires at the left and right sides of the loop?

• A)The electric field \(\vec { B }\) is directed upwards in both the right and left sides of the loop.
• B)The electric field \(\overrightarrow { \mathbf { v } }\) is directed upwards in the right side and downwards in the left side of the loop.
• C)The electric field \(\overrightarrow { \mathbf { E } }\) is directed upwards in the left side and downwards in the right side of the loop.
• D)The electric field \(\overrightarrow { \mathbf { E } }\) is directed downwards in both the right and left sides of the loop.
• E)There is no electric field present in any side of the loop.
