Induced EMF in a Solenoid
A solenoid has 500 turns, a length of 0.25 m, and a cross-sectional area of m². The current through the solenoid increases uniformly from 0 to 2.0 A in 0.10 s. What is the magnitude of the induced emf in the solenoid during this time?
A
1.0 × 10^-2 V
B
5.0 × 10^-3 V
C
2.5 × 10^-3 V
D
2.0 × 10^-2 V
