NEET 2015 Physics Induced E.M.F. MCQ Question
Type: MCQ-conceptual-Hard-Class 12
A conducting square frame of side 'a' and a long straight wire carrying current I are located in the same plane as shown in the figure. The frame moves to the right with a constant velocity v. The e.m.f. induced in the frame will be proportional to
A
1/x²
B
1/(2x - a)²
C
1/(2x + a)²
D
1/(2x - a)(2x + a)
Correct Answer
Option C
Detailed Explanation
The induced e.m.f. is due to the change in magnetic flux linked with the frame as it moves. The expression is derived from Faraday's law and the geometry of the setup.
