alleryFlux through a coil can be changed without moving it, by changing:
AIts weight
BIts price
CIts shape
DIts colour
Answer & Solution
Correct answer: C. Its shape
1. Flux is the product of field and enclosed area.
2. Shrinking or stretching the coil alters that area.
3. So changing the shape changes the flux.
4. The answer is its shape.
