What is the value of horizontal component of the earth's magnetic field at the magnetic poles?

A magnetic needle free to rotate about the vertical direction (compass ) point 3.5 west of the geographic north . Another magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 18^(@) with the horizontal . The magnitude of the horizontal component of the earth ' magnetic field at the place is known to be 0.40 G . what is the direction and magnitude of the earth's magnetic field at the place ?

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

A magnetic needle free to rotate in a vertical plane parallel to the magnetic meridian has its north tip pointing down at 22^@ with the horizontal. The horizontal component of the earth’s magnetic field at the place is known to be 0.35 G. Determine the magnitude of the earth’s magnetic field at the place.

A compass needle free to turn in a horizontal plane is placed at the centre of circular coil of 30 turns and radius 12 cm. The coil is in a vertical plane making an angle of 45^@ with the magnetic meridian. When the current in the coil is 0.35 A, the needle points west to east. Determine the horizontal component of the earth’s magnetic field at the location.

The horizontal component of the earth's magnetic field at a place is B_H and angle of dip is 60^@ What is the value of vertical component of earth's magnetic field at equator?

The ratio of vertical component to the horizontal component of earth's magnetic field at a given place is 1. What is the angle of dip at that place?

The line joining the points of horizontal component of earth's magnetic field is called

The vertical component of the earth's magnetic field at a given place is sqrt3 times its horizontal component. If total intensity of earth's magnetic field at the place is 0.4G, find the vale of the horizontal component of earth's magnetic field.

The vertical component of the earth's magnetic field at a given place is sqrt3 times its horizontal component. If total intensity of earth's magnetic field at the place is 0.4G, find the vale of angle of dip

The ratio of the horizontal component to the resultant magnetic field of earth at a given place is 1//sqrt2 . What is the angle of dip at that place?
