Question

The earth’s magnetic field: Select one:a.has a north magnetic pole at exactly the same spot as the geographical north poleb.causes compasses to workc.causes electromagnets to workd.all of the above e.none of the above

Answer 1

The geographic North Pole of the Earth is actually the magnetic South Pole and vice versa. In this sense a is false.

The compass is an orientation instrument that uses a magnetized needle to point to the Earth's magnetic north. Its operation is based on terrestrial magnetism, so it points to the magnetic south that corresponds to the geographical north and is unproductive in the north and south polar zones due to the convergence of the lines of force of the terrestrial magnetic field. So, the option b is true.

Answer:

b
