the materials are magnetic because of electromagnetic forces and this force is produced because of presence of positive and negative charges in them
Two so called rare earth materials that are magnetic are neodymium and samarium.
They use electromagnets to separate magnetic metals from non-magnetic metals/materials in scrapyards.
No, a magnet does NOT have the ability to attract materials that are NON-magnetic (unless it has something magnetic on it, or has magnetic material in it). Duhhh!!! I'm in seventh grade and even I know that!!! ; )
The word magnetic, or the word ferromagnetic refer to materials that can be attracted by magnets.
Magnetism is created by the synchronized spins of atoms with unbalanced electron clouds. The lowest energy states for these unbalanced atoms is to align themselves with nearby atoms and spin in unison, creating the magnetic field we are familiar with. Most atoms have balanced electrons, or have electron configurations which do not have low energy states when aligned, thus no inclination to spin together in large groups, and no magnetic field.
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.
ferromagnetic materials
Ferritic materials.
Four common magnetic materials that are strongly attracted to a magnet are iron, nickel, cobalt, and certain alloys of these metals. This is because these materials have unpaired electrons in their atomic or molecular structure, which creates a magnetic moment. When a magnet is nearby, the magnetic field of the magnet aligns the magnetic moments of these materials, causing them to be strongly attracted to the magnet.
I use a "magnet".
Usually not, but it depends on the types of materials in it (if they are magnetic then it will be).
