The angle of dip at a location in southern India is about `18^@`. Would you expect a greater or lesser dip angle in Britain?

Answer the following questions regarding earth's magnetism. a. A vector needs three quantities conventionally used to specify the earth's magnetic field. b. The angle of dip at a location in southern India is about 18^@ . Would you expect a greater or smaller dip angle in Britain ? c. If you made a map of magnetic field lines at Melboune in Australia, would the lines seem to go into the groung or come out of the ground ? d. In which direction would a compass free to move in the vertical plane point to , if located right on the geomagnetic north or south pole ? e. the earth' s field, it is claimed roughly approximates the field due to a dipole of magnetic moment 8 xx10^(22)JT^(-1) located at its centre. Check the order of magnitude of this number in some way. f. Geologists claim that besides the main magnetic N - S poles, there are several local poles on the earth's surface oriented in different directions. How is such a thing possible at all ?

The angle of dip at the magnetic equator is

At magnetic poles the angle of dip is

The angle of dip at a place where horizontal and vertical components of earth's magnetic field a equal is

A short bar magnet placed in a horizontal plane has its axis aligned along the magnetic north - south direction . Null point are found on the axis of the magnet at 14 cm from the centre of the magnet . The earth's magnetic field at the place if 0.36 G and the angle of dip is zero. What is the total magnetic field on the normal bisector of the magnet at the same distance as the null point (i.e., 14 cm) from hte centre of the magnetic ? (At null points , field due to a magnet is equal and opposite to the horizontal component of earth's magnetic field.)

Angle of dip at a place, wher horizontal and verical componet of earth's fiedl are qual is

If theta_1 and theta_2 be the apparent angles of dip observed in two vertical planes at right angles to each other,then the true angle of dip is give by :

A long straight horizontal cable carries a current of 2.5 A in the direction 10^@ north of east . The magnetic meridian of the place happens to be 10^@ west of the geographic meridian The earth's magnetic field at the location is 0.33 G , ad the angle of dip is zero. Locate the line of neutral points (ignore the thickness of the cable ) (At neutral points , magnetic field due to a current - carrying cable is equal and opposite to the horizontal component of earth's magnetic field ).

The contact angle between pure water and pure sliver is 90^@ If a capillary tube made of silver is dipped at one end in pure water, will the water rise in the capillary?
