Magnetism and Matter – Solutions
1) Answer the following questions regarding earth’s magnetism:
(a) A vector needs three quantities for its specification. Name the three independent quantities conventionally used to specify the earth’s magnetic field.
(b) The angle of dip at a location in southern India is about 180.
Would you expect a greater or smaller dip angle in Britain?
(c) 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?
(a) Following are the three independent quantities conventionally used to specify the earth’s magnetic field
(1) Angle of declination, D,
(2) Angle of dip, I and
