difference between natural magnets and artificial magnets in basis of their hardness
Answers
Answer:
A natural magnet is a magnet that occurs naturally in nature. Artificial magnets are magnets made by people. ... An example of a natural magnet is the lodestone, also called magnetite. Other examples are pyrrhotite, ferrite, and columbite.
Answer:
A natural magnet is a magnet that occurs naturally in nature. All natural magnets are permanent magnets, meaning they will never lose their magnetic power.
Natural magnets can be found in sandy deposits in various parts of the world. The strongest natural magnet material is lodestone, also called magnetite. This mineral is black in color and very shiny when polished. The lodestone was actually used in the very first compasses ever made. Because natural magnets are permanent magnets, if lodestone is allowed to freely spin, its north pole will always align itself with the Earth's geographic north pole.
When magnets are made by people, they are called artificial magnets. It's these magnets that are on your refrigerator door, and they have extra-strong magnetic power, like those really tiny super-strong magnets that you can buy from toy or science stores.
There are two types of artificial magnets: temporary and permanent. Temporary magnets are magnets that aren't always magnetic, but their magnetism can be turned on at will. Permanent magnets are those magnets whose magnetic strength never fades.
Permanent artificial magnets can also be made to suit the application they're for. They can be made so that the magnet's north and south poles are located at specific spots. For example, a ring magnet can be made so that the north pole is on the outside and the south pole is on the inside, or with the north pole on the inside and the south pole on the outside.
