Electromagnetic Induction question

2009 · Q140

NEETPhysicsElectromagnetic InductionMCQ+4 / −1
A rectangular, a square, a circular and an elliptical loop, all in the (x-y) plane, are moving out of a uniform magnetic field with a constant velocity. V→=vi^\overrightarrow V = v\widehat iV=vi. The magnetic field is directed along the negative z axis direction. The induced emf, during the passes of these loops, out of the field region, will not remain constant for
  1. A
    The circular and the elliptical loops
  2. B
    only the ellliptical loop
  3. C
    any of the four loops
  4. D
    the rectangular, circular and elliptical loops
View written solutionFree

Correct answer: A

Once a rectangular loop or a square loop is being drawn out of the field, the rate of cutting the lines of field will be a constant for a square and rectangle, but not for circular or elliptical areas.
