According to professor Claire Hart, who teaches a module on the psychology of attraction at University of Southampton, there are five main determinants of attraction: physical attractiveness, proximity, similarity, reciprocity and familiarity.

When two opposite magnetic poles are close, they attract each other. When like poles are pushed together, there is a force of repulsion. The rule for magnets is that like poles repel and unlike poles attract. Magnetic force in action. One of the most common everyday uses for magnets is in a simple compass.
When magnets are brought together, a north pole always attracts a south pole, while pairs of like poles repel each other. Bar magnets are the simplest permanent magnets. … Each student is asked to separate the objects into two categories based on whether the object will or will not be attracted to a magnet.
Magnetic materials are always made of metal, but not all metals are magnetic. Iron is magnetic, so any metal with iron in it will be attracted to a magnet. … Most other metals, for example aluminium, copper and gold, are NOT magnetic. Two metals that aren’t magnetic are gold and silver.
The Magnet Test
Most precious metals-like gold and copper-are nonmagnetic, and silver is no exception. Grab some magnets and see if they are drawn to your object. “Silver is not noticeably magnetic, and exhibits only weak magnetic effects unlike iron, nickel, cobalt, and the like,” says Martin.
Magnets are very useful in our lives. For example, we can use magnets to attract iron nails, iron keys, and iron scraps, etc. Magnets are usually made of iron, cobalt, nickel，and other atoms, which have special internal structures and magnetic moments. …
The magnetic field of a bar magnet is strongest at either pole of the magnet. It is equally strong at the north pole when compared with the south pole. The force is weaker in the middle of the magnet and halfway between the pole and the center.
