Hint: Magnes, a Greek shepherd, discovered magnets in Magnesia, Greece, 4000 years ago. Magnes found the lodestone, a naturally magnetic rock. It was used to determine directions on the soil in the form of a bar, hence the name lodestone, which means "the stone that leads." Magnetite is an iron compound found in lodestones. Magnesia or Magnesium is the source of the word magnetite. Magnets are called after the mineral magnetite. Natural magnets are rocks that have the property of attracting iron. Archimedes, an ancient Greek scientist, is thought to have used lodestone to extract nails from opposing ships, causing them to sink.
Complete answer:
Magnetic materials are those that are attracted by a magnet.
Magnetic substances are iron, nickel, and cobalt, as objects made of these materials are attracted by a magnet.
Note:
Application of Magnetic and Non-Magnetic Materials:
We may use a substance's magnetic and nonmagnetic qualities to make our lives easier. Some of them are as follows:
-If a big number of pins fall from the pin box into the ground, they can be easily gathered using a magnet because pins are made of iron, which is a magnetic material.
-When a carpenter combines iron nails with wood shavings, magnetic separation can readily separate them. A magnet is placed near the mixture. Iron nails are attracted to the magnet and stick to it, however, hardwood shavings, which are formed of non-magnetic material, are not.

Magnetic Materials: | Non-magnetic Materials: |
Magnetic materials are those that are attracted by a magnet. | Non-magnetic materials are those that are not attracted by magnets. |
Magnetic substances are iron, nickel, and cobalt, as objects made of these materials are attracted by a magnet. | Rubber, plastic, stainless steel, feather, paper, mica, gold, silver, leather, and other non-magnetic materials are examples. |
Magnetic materials can also be magnetized, or magnetic materials can be transformed into magnets. | Modern coins are composed of consistent mixes of several metals that render them non-magnetic. |
