What are magnetic poles? Why are they called north pole and south pole?

Expert Solution

a) For a magnet :

Magnetic poles of a magnet are the areas near the ends of the magnet where the magnetic field due to the magnet is strongest. For any magnet there are two points one at each end of the magnet where the magnetic field is srrongest.

These two points one at each end of the magnet are called magnetic poles.

When a magnet is freely suspended one of its end point towards the geographic north pole of the earth , this pole of the magnet is called north pole and the magnetic pole at the other end of the magnet is called south pole of the magnet.

b) For the earth :

For the earth magnetic poles are the regions near the geographic poles of the earth where the magnetic field of the earth becomes vertical. When a dip circle is taken to the magnetic poles of the earth , the needle of the dip circle becomes vertical.

Magnetic North pole of the earth is near the geographic south pole of the earth and Magnetic south pole of the earth is near the geographic north pole of the earth

The earth’s north pole is a magnetic south pole. The field above the pole is ~0.05mTesla. A proton from the sun with a velocity of 1,000,000 m/s enters this magnetic field. a) Find the force on the proton if the velocity is perpendicular to the Magnetic field. b) This is a centripetal force that makes them take circular orbits. Find the radius of the orbit.

You are designing magnetic motors. A colleague1 insists that like magnetic poles attract— north poles attract north poles and south poles attract south poles. You feel the need to remove this idea from his head. You possess three unlabeled bar magnets (that is, you don’t know which ends are N or S). Surely that will be enough. . .
