What is a force that pulls magnetic materials across a distance?
Magnetism is a force that causes magnetic objects to move toward a magnetic force. The force is felt strongest on magnets which experience what is known as ferromagnetism, the strongest type of magnetism. When it is liquefied and cooled, oxygen can exhibit properties of magnetism. There are also non-magnetic substances that are not affected by a magnetic field or magnetism, these include plastics, gases, copper and aluminum,.
What are the physical properties of a magnet?
Magnetism is a physical property because attracting something to a magnet does not change the substance (change of the composition) itself and doesn't involve chemical reactions. The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, the magnetism doesn't change the substance itself.
What magnetic material is easy to magnetize but loses its magnetism easily?
Soft iron is a good example of a material that can be strongly magnetized by an external magnetic field, but which loses most (or nearly all) of its magnetism as soon as the external field is removed. Generally, materials classed as Paramagnetic exhibit this behaviour. Many Ferromagnetic materials are designed to behave this way, such as the Ferrite cores of tuning coils in radio receivers.
Permanent magnets can lose their magnetic properties if they are heated Explain why magnetic properties are lost under these conditions?
Ferro magnetic materials that exhibit ferro magnetism loose their properties by converting themselves into diamagnetic substances. The magnetic properties of ferro materials are due to strong magnetic domains inside the material. A domain is nothing but a group of molecules having same magnetic orientation. When heated these molecule due agitation caused by internal energy scatter and the phenomenon of domains no longer exist and hence they act as diamaterials loosing magnetism.
Is a magnet a rock?
No. It is not a rock. However there are rocks that are magnetic, have magnetism. Magnetism is one-half of the fundamental force called electro-magnetism. That's why we can cause some things to move using magnets.

Is hydrogen magnetism?
no
The piece of metal is magnetic is that physical property or chemical property?
Magnetism is a physical property that is mediated by magnetic fields.The magnetic state of a material depends on temperature (and other variables, such as pressure and the applied magnetic field), so a material may exhibit more than one form of magnetism depending on its temperature, etc. However, a material's magnetism doesn't change the composition, and doesn't involve a chemical reaction.

true
Is iron magnetic?
Yes, iron is a magnetic material. It is an element by itself by alloys containing iron would also exhibit varying degrees of magnetism. The other magnetic elements include cobalt and nickel.
What is the difference between a permanent magnet and a temporary magnet?
Temporary magnet: good example is an electromagnet. It maintains magnetic attraction only so long as an electric current surrounds it. Permanent magnet: most common. Example: bar magnet. Will maintain magnetic properties for quite a while, although they can be eventually demagnetized.
Spin causes electrons to?
Spin causes electrons to exhibit magnetism.
