Question
The magnetic field in a coil of 100 turns and 40 cm2 an area is increased from 1 tesla to 6 tesla in 2 second. The magnetic field is perpendicular to the coil. The e.m.f. generated in it is : -
Options
A.104 V
B.1.2 V
C.1.0 V
D.10-2 V
Solution
e = 
= (100) (40 × 10-4) 
= 0.8 volt ≈ 1volt
= (100) (40 × 10-4) = 0.8 volt ≈ 1volt
