The total charge induced in a conducting loop when it is moved in magnetic field depends on
Options
- Athe rate of change of magnetic flux
- Binitial magnetic flux only
- Cthe total change in magnetic flux
- Dfinal magnetic flux only
Correct answer
C. the total change in magnetic flux
Step-by-step solution
Induced emf is given by e=- d d t As, i= e R =- 1 R d d t Total charge induced = i d t aligned & =- 1 R d d t d t=- 1 R _ ₁ ^ ₂ d & = 1 R _ ₁ ^ ₂ d = 1 R ( ₁- ₂ ) aligned Thus, the induced charge in a conducting loop, moving in a magnetic field depends on the total change in magnetic flux.
