A rectangular, a square, a circular and an elliptical loop, all in the plane, are moving out of a uniform magnetic field with a constant velocity, vi. The magnetic field is directed along the negative -axis direction. The induced emf, during the passage of these loops, out of the field region, will not remain constant for
Options
- Athe rectangular, circular and elliptical loops
- Bthe circular and the elliptical loops
- Conly the elliptical loop
- Dany of the four loops
Correct answer
B. the circular and the elliptical loops
Step-by-step solution
Area coming out per second from the magnetic field is not constant for elliptical and circular loops, so induced emf, during the passage of these loops, out of the field resion will not remain constant for the circular and the elliptical loops.
