Magnetic Flux & Faraday's Law
Whenever a magnet is moved either towards or away from a conducting coil, magnetic flux linked with the coil changes. This change is dependent on
(a) the strength of the magnetic field.
(b) the area of cross-section of the coil.
(c) the resistance of the coil.
(d) the number of turns in the coil.
Show answer and solution
Answer: (c)
- Flux linkage .
- It depends on field strength , area and number of turns .
- Resistance affects only the induced current, not the flux.
- So the answer is (c) (a), (b), (d).
