Calculate the magnetic flux through a circular loop of diameter 40cm when placed vertically at a place Where horizontal component of the earth’s magnetic field is `2.0 xx 10^-5T`.

What is the angel of dip at a place where the horizontal and vertical components of the Earth's magnetic field are equal?

At a place on earth 's surface where the horizontal and vertical components of earth's magnetic field are equal ,

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^(@) .

A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip down at 60^@ with the horizontal. The horizontal component of the earth's magnetic field at the place is known to be 0.4G. Determine the magnitude of the earth's magnetic field at the place.

Define angel of dip at a place. What will be the value of the angle at the poles and the equator of the earth? Aat what place on the earth's surface will the horozontal component of the eath's magnetic field and is verticle component ne equal?

Statement I : The intensity of earth's magnetic field may be different even if the horizontal component of earth's magnetic field is the same at two different places . Statement II : the horizontal component of earth's magnetic field is Isintheta where I is the intensity of earth's magnetic field and theta is the angle of dip at a place .

The vertical component of earth’s magnetic field is zero at a place when angle of dip is—

At a place , the angle of declination is 30^(@)E and the angle of dip is 45^(@)N . Determine the horizontal and vertical components of the geomagnetic intensity in geographical meridian at that place. Given , the horizontal component of earth's magnetic field at that place = 0.3 Oe .
