A circular coil of radius 10 cm, 500 turns and resistance `2 Omega` is placed with its place,perpendicular to the horizontal component of the earth's magnetic field. It is rotated about its vertical diameter through `180^@` in 0.25 sec . Estimate the magnitudes of the EMF and current induced in the coil .[horizontal component of the earth's magnetic field at the place is `3.0 times 10^-5 T`).

At a certain place the horizontal component of earth's magnetic field is (1)/(sqrt3) times the vertical component. The angle of dip at that place is

At a certain place, the angle of dip is 60^(@) and the horizontal component of the earth's magnetic field (B_(H)) is 0.8xx10^(-4) T. The earth's overall magnetic field is

The horizontal component of the earth's magnetic field at a certain place is 2.6 xx 10^(-5) T and the angle of dip is 60^(@) . What is the magnetic field of the earth at this location ?

A short bar magnet of magnetic moment 0,21 A - m^(2) is placed with its axis perpendicular to the direction of the horizontal component of the earth 's magnetic field .The distance of the point on the axis of the magnet from the centre of the magnet where the resultant magnetic field is inclined at 45^(@) with the horizontal component of the earth's field direction is (horizontal component of the earth's magnetic field 4.2xx10^(-5)

In the magnetic meridian of a certain place, the horizontal component of the earth's magnetic field is 0.26 G and the dip angle is 60^(@) . What is the magnetic field of the earth at this location ?

In the magnetic meridian of a certain place the vertical component of the earth's magnetic field is 0.3464 G and the dip angle is 30^(@) . The horizontal component of the earth 's magnetic field at this location is

A current canying straight wire is placed along east-west and current is passed through it eastward . The direction of the force act on it due to horizontal component of earth's magnetic field is
