An aeroplane is travelling at the speed of `360 km//hr` along the horizontal to the earth surface'. What is the induced potential developed between the ends of th'e wing 5 m long, if the earth’s magnetic field at the location has-a magnitude of `4 xx 10^-4 wb//m^2` and dip angle is `30^@`?

A jet plane is travelling toward, 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^(-4)T and the dip angle is 30^@ .

An aeroplane is flying horizontally from west to east with a velocity of 900 km/h. Calculate the potential difference developed between the ends of its wings having a span of 20 m. The horizontal component of the Earth's magnetic field is 5xx10^(-4)T and the angle of dip is 30^(@) .

At any place the angle of dip is 30^@ . If the horizontal component of earth’s magnetic field is 0.5 Oe then, What Is the value of earths magnetic field at that point?—

A straight conductor of length 10 cm is rotating in a vertical plane with one of its ends fixed. The angular velocity is 10 rad . s^(-1) . What is the value of emf (in muV ) induced between the two ends of the conductor if the horizontal component of earth's magnetic field at the place is 10^(-4)T ?

An aeroplane has its wing span of 36m.If if move with a velocity of 400 km//hr ,what will be its induced emf? (B_v=4xx 10^-5T) -

Angle of declination at a place is 20^(@) What will be the horizontal and vertical components of earth's magnetic field on the geographical meridian at that place? Given H=2xx10^(-5)T and angle of dip at that place 60^(@)

A long straight horizontal cable carries a current of 2.5 A in the direction from 10^(@) in the magnetic meridian of the place happens to be 10^(@) west of the geographic meridian . The earth's magnetic field at the location is 0.33 g and angle of dip is zero . Locate the line of neutral point . (ignore the thickness of the cable .)
