A circular coil of radius 10 cm, 500 turns and resistance 2 \(\Omega\) is placed with its plane perpendicular to the horizontal component of the earth's magnetic field. It is rotated about its vertical diameter through 180o in 0.25 s. The current induced in the coil is
(Horizontal component of the earth's magnetic field at the place is 3.0 \(\times\) 10-5 T)
- 1.9 \(\times\) 10-3A
- 2.9 \(\times\) 10-3A
- 3.9 \(\times\) 10-3A
- 4.9 \(\times\) 10-3A
Answer
(A) 1.9 10 -3 A
