In a magnetic material that is not a magnet, magnetic domains are arranged in random fashion canceling the net magnetic field. If such a material, like an iron rod, is exposed to a strong magnetic field, the domains will arrange themselves in the direction of the applied field and hence object will become magnetized.

What is a example of induced magnetism?
Magnetic fields can be generated by either a permanent magnet, or generating it by electrical flow such as through a coil. If the magnet is then put near another material such as iron... the iron will then also start exhibiting an INDUCED magnetic field. Induction motors operate on this principle with the armature being non-magnetic... and the motor operates by inducing a magnetic field into the armature. Superconductors are unique that a magnet will induce an opposite magnetic field in them, and will be repulsed by the magnet.
Is lead magnetic or non magnetic?
No, iron,cobalt,and nickel are the only known magnetic substance.
What metal has the lowest magnetic retentivity?
Generally, non-magnetic metals like aluminum and copper have low magnetic retentivity compared to magnetic materials like iron and nickel. They do not retain magnetism once a magnetic field is removed.
Can magnetism pass through magnetic materials?
Yes, magnetism can pass through some magnetic materials such as iron or steel, but may be blocked or weakened by others like nickel or cobalt. The ability of magnetism to pass through a material depends on its magnetic permeability.
What is the difference between magnetic and non magnetic iron?
Magnetic iron contains iron atoms that are aligned in a magnetic field, making it attracted to magnets. Non-magnetic iron does not exhibit this property and has iron atoms that are not aligned in a magnetic field, thus not being attracted to magnets.
What is magnetism of gold?
Gold is essentially non-magnetic.
What is golds magnetism?
Gold is essentially non-magnetic.
Why doesn't the iron in human bodies attract magnetic objects?
There are two types of iron: magnetic and non-magnetic iron. The iron in your body is the non-magnetic kind.
Is a key magnetic?
No keys are not magnetic at all. Keys do not have iron in them and magnets are attracted to iron.
Why isn't rusted iron as attracted to a magnet as non rusted iron?
Rusted iron, or iron oxide, does not contain the same magnetic properties as pure iron. The presence of rust creates a barrier between the iron atoms and the magnetic field, reducing the overall magnetism. Additionally, the rust itself is not magnetic, further decreasing the attraction to a magnet.
Is ice magnetic?
No, ice is not magnetic. Magnetism occurs in materials that have unpaired electrons with aligned spins, such as iron or nickel. Ice is a non-magnetic material composed of water molecules arranged in a crystalline structure.
Is silver magnetic or a non magnetic?
Of course not. Fe (iron) and steel are attracted to magnets. Silver is not
