Can a strong magnet be suck the platinum ring?

Can't suck Platinum
The iron -sucking the name magnet of the iron
M magnet is a kind of magnet.

M magnet can suck metals such as iron, nickel, and cobalt, commonly known as iron -absorbing stone. It can be divided into common permanent magnets, as well as magnetic electromagnets with magnetic properties. If the magnet is made into a stick or needle, it will naturally point to the Antarctic and Arctic of the Earth. Magnetic is divided into large magnets and small magnets.

This of large magnet magnets is widely used. The electromagnets are used to make the crane to transport steel. After power -on, it becomes a powerful magnet, so it can suck the bulky steel. Just cut off the power when putting down the steel.

Compared with large magnets, the compass is small and light, and the magnetism is much weaker. The role of the compass is not to absorb iron, but to reflect the magnetic force of the earth.

The properties of magnets such as iron, cobalt, nickel and other substances are called magnetic. The region with strong magnetic properties at both ends of the magnet is called the magnetic pole, one end is the Arctic (N pole), and the one end is Antarctic (S pole). Experiments have shown that homosexual magnetic poles are mutually exclusive and the heterosexual magnetic poles attract each other.

The original magnetic magnets with two heterosexual magnetic poles in the iron. When the effect of an external magnetic field, these original magnetic arrangements are disordered. Their magneticity offsets each other and does not display magneticity to the outside. When the iron is close to the magnet, these primary magnets are arranged neatly under the action of magnets, so that one end of the magnet is attracted to each other with the polarity opposite to the polarity of the magnet. This shows that the existence of the original magnet can be magnetized by magnets. Copper, aluminum and other metals have no primary magnet structure, so they cannot be attracted by magnets.
