magnetic substances are those substances which are strongly or weakly attracted by magnetic force (B) like paramagnetic(strongly attracted by B), ferromagnetic(weakly attracted by B) , diamagnetic (repel by B)
They are Colbalt,nickel, iron and copper.
The 4 magnetic substances are : Nickel
Steel
Iron
Cobalt
These are the only 4 magnetic substances
Cobalt, Steel, Nickel and Iron.
Iron, cobalt, nickel, steel
ferromagnets
Iron, Nickel, Cobalt and Gadolinium are the 4 metallic elements with strong magnetic properties but their are more materials than can be magnetic. Steel is an iron alloy that is magnetic. Stainless steel is an alloy of iron, chromium and maybe other materials. Not all stainless steel is magnetic. The amount of magnetic material in it (iron, nickel) determines if it is magnetic or not. ALNICO magnets made of Aluminum, Nickel, and Cobalt are very strong permanent magnets. Ceramic magnets are made of a powdered magnetic material mixed with a ceramic material that gives them a softer texture that will not scratch surfaces and they are popular as refrigerator magnets.
If two materials have a weak magnetic domain then their lines of force will be sketched as farther apart. This is the convention for drawings of magnetic fields.
Materials which retain their magnetism and are difficult to demagnetize are called hard magnetic materials. These materials retain their magnetism even after the removal of the applied magnetic field. Hence these materials are used for making permanent magnets. In permanent magnets the movement of the domain wall is prevented. They are prepared by heating the magnetic materials to the required temperature and then quenching them. Impurities increase the strength of hard magnetic materials. Soft magnetic materials are easy to magnetize and demagnetize. These materials are used for making temporary magnets. The domain wall movement is easy. Hence they are easy to magnetize. By annealing the cold worked material, the dislocation density is reduced and the domain wall movement is made easier. Soft magnetic materials should not possess any void and its structure should be homogeneous so that the materials are not affected by impurities.
MAGNETIC: Magnatite, Iron, Cobalt, Nickel, Manganese, Chromium. NON MAGNETIC: hydrogen, water, steel, graphite, diamond, silicon, carbon dioxide, methane, ethane, propane, and almost any other substance you can think of
i do not know. that is why i told you
the 4 magnetic materials are iron, steel, copper and nickel
the 4 magnetic materials are iron, steel, copper and nickel
Here's the answer plain and simple, no. .
Non-magnetic materials are referred to as diamagnetic.
Magnetic: Fridge magnet Non magnetic: Milk

It's not the material it's whats in iron and cobalt makes materials magnetic
Magnets have magnetic force in them, obviously, to attract or repel magnetic materials. The materials could not be attracted without the magnetic force because the magnet forces the magnetic material towards it.
The magnetic materials which can magnetise and de-magnetise easily are called "soft magnetic materials" example:-ferrites,iron-cobalt alloy. The magnetic materials which cannot magnetise and de-magnetise easily are called "hard magnetic materials" example:-aluminium(al),nickel-cobalt alloy.
