Answer the question regarding earth's magnetism:
The angle of dip at a location in southern India is about `18^@.` Would you expect a greater or smaller dip angle in Britain?

Answer the question regarding earth's magnetism: If you made a map of magnetic field lines at Melbourne in Australia, would the lines seem to go into the ground or come out of the ground?

Answer the question regarding earth's magnetism: 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?

Answer the question regarding earth's magnetism: The earth's field, it is claimed, roughly approximates the field due to a dipole of magnetic moment 8 xx 10^(22) JT^(-1) located at its centre. Check the order of magnitude of this number in some way.

A long straight horizontal cable carries a current fo 2.5 A in the direction 10^(@) south of west to 10^(@) north of east . The magnetic meridian of the plane happens to be 10^(@) west of the geographic meridian . The earth's magnetic field at the location is 0.33 G , and the angle of dip is zero. Locate the line of neutral points.

At certain place, the horizontal component of earth.s magnetic field is 3.0 G and the angle dip at that place is 30^(@) . The magnetic field of earth at that location

A telephone cable at a place has four long straight horizontal wires carrying a current of 1.0 A in the same direetion east to west. The earth's magnetic held at the place is 0.39 G, and the angle of dip 35^@. The magnetic declination is nearly zero. What are the resultant magnetic felds at points 4.0 cm below the cable?

The earth’s magnetic field at a certain place has a horizontal component of 0.3 G and total strength 0.5 G. Find angle of dip in tan^-1

A jet plane is travelling towards west at a speed of 1800 km/h. What is the voltage difference developed between the ends of the wing having a span of 25 m, if the Earth’s magnetic field at the location has a magnitude of 5 x× 10^(-4) T and the dip angle is 30^@ .
