railway RRB Technician Grade 1 Mock Test 2024 Physics Electromagnetic Induction and Inductance Magnetic Flux
A circular loop of radius a, area A and resistance ‘R’ is placed in a magnetic field B = B0 sinωt with its plane perpendicular to the field. The value of induced current in the loop will be
1
\(\frac{B_0A}{\omega R} \sin \omega t\)
2
\(\frac{AB_0}{\omega R} \cos \omega t\)
3
\(\frac{AB_0\omega}{ R} \cos \omega t\)
4
\(-\frac{AB_0\omega}{ R} \cos \omega t\)
