A jet plane Is travelling towards west at a speed of 1800 km/h. What Is the voltage difference developed between the ends of the wing 25m longl if the earth.s magnetic field at the location has a magnitude of `5.0x10^-4` and the dip angle is 30.

A jet plane is travelling.towards west at a speed of 1800 km//h . What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth’s magnetic field at the location has a magnitude of 5xx10^-4T and the dip angle Is 30^@ .

Motion of a conductor in a magnetic field induces an emf across its ends.An aeroplane is flying horizontally from west to east with a velocity of 720 km/h. Calculate the emf. induced between the ends of ts wings having a span of 25m. The vertical component of earth.s magnetic field at the place is 2.19*10^-5 T

A horizontal straight wire 10m long extending from east to west is falling with a speed of 5.0ms^-1 at right angles to the horizontal component of the earth.s magnetic field 0.3x10^10-4 Wbm^2?. What is the direction of the e.m.f.?

A horizontal straight wire 10m long extending from east to west is falling with a speed of 5.0ms^-1 at right angles to the horizontal component of the earth.s magnetic field 0.3x10^10-4 Wbm^2?. What is the instantaneous value of the e.m.f. in- duced in the wire?

A shortbar magnet placedin ahorizontal plane has Its axis aligned along the magnetic north-south .direction. Null points are found on the axis of themagnet at 14 cm from the centre of the magnet. The earth’s magnetic field at the place is 0.36 G and the angle of.dip is zero. What Is the total magnetic field on the normal bisector of the magnet at the same distance as the null”point (i.e, 14 cm) from the centre of the magnet? (At null points, field due to a magnet Is equal and opposite to the horizontal component of earth’s magnetic field)
