A) Zero in loop 1 and zero in loop 2
B) \[-\frac{d\overset{\to }{\mathop{B}}\,}{dt}\pi {{r}^{2}}\text{in loop 1 and}\,-\frac{d\overset{\to }{\mathop{B}}\,}{dt}\pi {{r}^{2}}\,\text{in}\,\text{loop}\,\text{2}\]
C) \[-\frac{d\overset{\to }{\mathop{B}}\,}{dt}\pi {{r}^{2}}\text{in loop 1 and zero in loop 2}\]
D) \[~-\frac{d\overset{\to }{\mathop{B}}\,}{dt}\pi {{r}^{2}}\text{in loop 1 and zero in loop 2}\]
Correct Answer: D
Solution :
Magnetic flux linked with area of loop 1 is\[\pi {{r}^{2}}\] So emf in loop 1 is \[-\frac{d\overset{\to }{\mathop{B}}\,}{dt}\pi {{r}^{2}}.\] Magnetic flux linked with area of loop 2 is zero So emf in loop 2 = 0You need to login to perform this action.
