Define the components of earths magnetic field.

A short bar magnet placed on a horizontal plane has its axis aligned along the magnetic north- south direction . Null points are found on the magnet . The earth's magnetic field at the place is 0.36G . What is the magnet at the total magnetic field on the normal bisector of the same distance as the null points (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 . )

At tow places , the angels oa dip are 30^(@) N and 30^(@) S and the earth 's magnetic filed is 0.42 Oe . Determine the horizontal and the vertical components of earth's magnetic field at these two places and also indicate their directions with the help of a diagram .

A horizontal straight wire 5 m long extending from east to west is falling with a speed of 10 m/s at right angles to the horizontal component of earth's magnetic field 0.40xx10^(-4)Wb.m^(-2) . What is the direction of the emf?

A horizontal straight wire 5 m long extending from east to west is falling with a speed of 10 m/s at right angles to the horizontal component of earth's magnetic field 0.40xx10^(-4)Wb.m^(-2) . Which end of the wire will be at higher potential? (Neglect acceleration due to gravity.)

A horozontal straight wire 5m long extending from east to west is falling with a speed of 10 ms^-1 at right angles to the horizontal component of earth's magnetic field 0.40xx10^-4 Wb m^-2 . Find the instantaneous value of emf induced in the wire

Explain horizontal component of Earth's magnetic field.

At a place , the horizontal component of earth's magnetic field is B and angle of dip is 60^(@) . What is the value of horizontal component of earth's magnetic field at equator ?
