coil is taken out of the field, 32C charge flows through
it. The magnetic induction field strength is.
1) 6.55 T
2) 5.66 T
3) 0.655 T
4) 0.566 T
with explanation

Answer 1

Answer:

A coil of 40Ω resistance has 100 turns and radius 6mm us connected to ammeter of resistance of 160ohms. Coil is placed perpendicular to the magnetic field. When coil is taken out of the field, 32μC charge flows through it. The intensity of magnetic field will be.
