Magnetic meridian is a

A vibration magnetometer placed in magnetic meridian has a small bar magnet. The magnet executes oscillations with a time period of 2 sec in earth's horizontal magnetic field of 24 microtesla. When a horizontal field of 18 microtesla is produced opposite to the earth's field by placing a current carrying wire, the new time period of magnet will be

Angle between magnetic meridian and geographical meridian is called

Define magnetic axis, geographic axis, magnetic meridian and geographical meridian.

A magnet is suspended in the magnetic meridian with an untwisted wire. The upper end of wire is rotated through 180^(@) to deflect the magnet by 30^(@) from magnetic meridian. When this magnet is replaced by another magnet, the upper end of wire is rotated through 270^(@) to deflect the magnet 30^(@) from magnetic meridian. The ratio of magnetic moment of magnets

A dip circle is at right angle to the magnetic meridian. What will be its apparanet dip?

At 52^@ from the magnetic meridian, a magnetic needle in a vertical plane makes an angle of 45^@ with the horizontal plane. Find the actual angle fo dip at that place.

A bar magnet 30 cm long is placed in the magnetic meridian with its north towards south of the earth. If the neutral point is obtained 30 cm from the magnet, find magnetic dipole moment and pole strength of the magnet.

The true value of dip at a place is 45^@ If the plane of the dip circle is turned through 60^@ from the magnetic meridian, what will be the apparaent value of the dip?
