a) The earth's cor is known to contain iron. Yet geologists do not regard this as a source of earth's magnetism. Why? b)The charged currents in the outer conductiong regions of the eath's core are thought to be responsible for earth's magnetism . What might be the 'battery'(i.e the source of energy) to sustain these currents? c)Geologists say that besides main magnetic N-S poles , there are several local poles on earth's surface oriented in different directions. How is such a thing possible? d) Is a magnetic field confiuration with three poles possible? Suggest one examples to support your answer.
