A material is said to be magnetic if a large percentage of the atoms of which it is comprised are capable of being aligned together such that the individual magnetic fields of individual atoms can reinforce each other. Nickel, Iron, Cobalt, Gadolinium and most of their alloys are highly magnetic. ______________________________________________________________________ There Physical Properties and if it is electrically charged in some cases.

Why are some materials magnetic and others are non-magnetic?
Almost all magnetism is caused by electrons.Individual electrons have an intrinsic magnetic moment.In an atom, the electron's angular motion around the nucleus also causes a magnetic moment.Since all solid materials are composed of atoms and include electrons, the question becomes: why aren't all materials magnetic?Many atoms only have paired electrons, with the intrinsic magnetic moment of each electron cancelled out by the intrinsic magnetic moment of its paired electron.Many atoms only have "filled sub-shells", which have zero net angular motion.Atoms with either unpaired electrons, or unfilled sub-shells, or both, are inherently magnetic. However, in many materials, the magnetic moments of these atoms point in random directions, so they cancel out and the bulk material is nonmagnetic.It is to do with the pairing of electrons and their dipoles. Basically metals with uneven electrons or half shells are magnetic. Three main metals that are Iron, Cobolt and Nickel. With Iron being the main one.Hope this helps! =]
If two materials have a weak magnetic domain?
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.
What is the difference between hard and soft magnetic materials?
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.
What are magnetic and non - magnetic materials?
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
Which type of materials are magnetic?
i do not know. that is why i told you
Why four magnetic materials are strongly attracted to the magnet?
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.
Do magnetic materials rust?
They can, but you have to understand that magnetism and oxidation (the process that causes rust) are unrelated.
What are the effects of the magnetic field that we can see?
For example, you can see a magnet making another magnet - or certain magnetic materials, such as iron - move.
Causes of Magnetic Drift?
causes of magnetic drift causes of magnetic drift causes of magnetic drift
Why do magnets only attract certain materials?
Ferromagnetic materials are attracted to magnets because their electrons spin and the resulting “magnetic moments” align easily, and retain that alignment even without an external magnetic field. ... Essentially, any alloy composed of ferromagnetic materials will also be magnetic.
What three elements do magnetic materials contain?
Magnetic materials may contain any mixture of certain elements. Three of the most common elements are iron, nickel and cobalt.
Difference between magnetic and non-magnetic materials?
Simple answer: Magnetic materials are affeted by magnets while non magnetic materials are not Advanced: Magnetic (or paramagnetic) materials have unpaired electrons, causing atoms to align in a certain pattern when a magnet is introduced
Are materials with magnetic properties magnetic materials?
Here's the answer plain and simple, no. .
What are non magnetic materials called?
Non-magnetic materials are referred to as diamagnetic.

What material is used in electro magnets?
The magnetic field in an electromagnet is actually produced by the coil of wires with a current running through it. However certain materials, termed 'ferromagnetic' materials concentrate the magnetic flux when a rod of the material is placed within the coil (termed the 'magnetic core'). The most common of materials used for this have been iron based.
