Question
1. Magnetic fields create magnetic field lines, just as an electric field creates electric field lines. The direction of the magnetic field is the direction in which the north pole of a compass points when placed at a location. Which pole of a compass needle points to the North geographic pole of Earth? Explain. [5 pts) North geographic pole South geographic pole 2. Magnetic materials are usually made of ferromagnetic atoms (Fe, Co, Ni) which each act like microscopic bar magnets. If the "direction" of the atoms are disordered, the material will be attracted to a magnet but does not generate a net magnetic field. If the atoms are ordered, then the material will be a strong magnet. Strong magnet Magnetic material What do you think would happen to a strong magnet if it is heated? Describe this in ternas of the atoms within. [5 pts]Explanation / Answer
1) North Pole of the compass needle points to the north geographic pole of the Earth.
A magnetic compass points to the earth's magnetic poles, which are not the same as earth's geographic poles. Furthermore, the magnetic pole near earth's geographic North Pole is actually the south magnetic pole. When it comes to magnets, opposites attract. This fact means that the north end of a magnet in a compass is attracted to the south magnetic pole, which lies close to the geographic North Pole.
