Question

The total charge induced in a conducting loop when it is moved in magnetic field depend on

• A. The rate of change of magnetic flux
• B. Initial magnetic flux only
• C. The total change in magnetic flux and resistance
• D. Final magnetic flux only

Answer 1

Answer: (C)

The total change in magnetic flux and resistance

Answer 2

$\mathrm { q } = \int \mathrm { Idt } = \frac { 1 } { \mathrm { R } } \int \varepsilon \mathrm { dt } = \frac { 1 } { \mathrm { R } } \int \frac { \mathrm { d } \phi } { \mathrm { dt } } \mathrm { dt } = \frac { 1 } { \mathrm { R } } \int \mathrm { d } \phi$

Hence total charge induced in the conducting loop depend upon the total change in magnetic flux and resistance.
