Calculate the angle of dip, if a dip needle oscillating in a vertical plane makes 40 oscillations per minute in a magnetic meridian and 30 oscillations per minute in a vertical plane at right angle to the magnetic meridian.

The angle of dip if dip needleoscillating in vertical plane makes 40 oscillations per min in a magnetic meridian and 30 oscillations per minute in vertical plane at right angle to the magnetic meridian is

A dip needle free to move in a vertical plane perpendiculr to the magneetic meridian will remain

The needle of a dip circle completes 4 oscillations in one minute while vibrating in a vertical plane at right angles to the megnetic meridian. The same needle oscillates 3 times per minute in a horizontal plane at the same place. Find the value of dip at the place

A magnet is suspended in such a way that it oscillates in the horizontal plane. It makes 20 oscillations per minute at a place where dip angle is 30^(@) and 15 oscillations minute at a place where dip angle is 60^(@) . The ratio of total earth's magnetic field at the two places is
