Teaching RPSC School Lecturer Mock Test Series 2024 Physics Moving Charges and Magnetism Magnetic Force on a Current-Carrying Wire
A conducting circular loop of radius \(\frac{10}{\sqrt \pi}\) cm is placed perpendicular to a uniform magnetic field of 0.5 T. The magnetic field is decreased to zero in 0.5 s at a steady rate. The induced emf in the circular loop at 0.25 s is:
1
emf = 1mV
2
emf = 5mV
3
emf = 100mV
4
emf = 10mV
