Question

The magnetic flux in a coil of 100 turns increases by $12\times {10}^3$ Maxwell in 0.2 second due to the motion of a magnet. The emf induced in the coil will be

• A. 6 V
• B. 0.6 V
• C. 0.06 V
• D. 60 V

Answer 1

The correct option is C 0.06 V

$emf=$ rate of change of flux $\times$ number of turns $=\frac{12\times {10}^3\times {10}^{-8}}{0.2}\times 100=0.06V$

1 Maxwell = ${10}^{-8}$ weber
