NEET2009PhysicsElectromagnetic InductionActual
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 =v i . The magnetic field is directed along the negative z-axis direction. The induced emf, during the passage of these loops, come out of the field region, will not remain constant for :
Options
- Aany of the four loops
- BThe rectangular, circular and elliptical loops
- CThe circular and the elliptical loops
- DOnly the elliptical loop
Correct answer
C. The circular and the elliptical loops
Step-by-step solution
Out of the four structures, when the circular and elliptical loops come out from the field, equal are is not traced in equal interval of time. So any induced in both is not constant.
