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 horizontal component of earths's magnetic field at a place is 0.3 xx 10^-4T . If the angle of dip is 60^@ , what is the total earth's magnetic field?

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

Define parameters of earth's magnetic field.

What is the angle of dip at a place where the horizontal and vertical component of earth magnetic field are equal?

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.

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 ?

What is the cause of earth's magnetism?
