A conducting square loop of side L and resistance R moves in its plane with a uniform velocity v perpendicular to one of its sides. A magnetic induction B constant in time and space, pointing perpendicular and into the plane of the loop exists everywhere. The current induced in the loop is

• A

  $\frac{\mathrm{Blv}}{\mathrm{R}}\text{ clockwise }$

• B

  $\frac{\mathrm{Blv}}{\mathrm{R}}\text{ anticlockwise }$

• C

  $\frac{2\mathrm{Blv}}{\mathrm{R}}\text{ anticlockwise }$

• D

  Zero
