Fig. shows two positions of a loop PQR in a perpendicular uniform magn

1.	Fig. shows two positions of a loop PQR in a perpendicular uniform magnetic field. In which position of the coil is there an induced emf?
Answer» In position (i), the coil remains as such in magnetic field, so there is no magnetic flux change in the coil, hence no emf is induced. In position (ii) the coil is coming out of the magnetic field, so the magnetic flux linked with it decreases and so an emf is induced in the coil.

Answer»

In position (i), the coil remains as such in magnetic field, so there is no magnetic flux change in the coil, hence no emf is induced.

In position (ii) the coil is coming out of the magnetic field, so the magnetic flux linked with it decreases and so an emf is induced in the coil.

While sitting a lawn, Ashok and his friends saw that a bird was sitting on high voltage wire. They observed that when a current passed through the wire, the bird sitting on it flew away. People along with both of them gave their opinions and reasons for it, but nobody was able to give a proper balanced option, but in the last Ashok explained the reason behind it.
