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
Magnetic materials are attracted to magnets. These primarily include: steel, cobalt and nickel and some of their alloys magnets attract various other substances besides pure iron . Some ceramics have slight attraction to magnets.
Non magnetic materials are not attracted to magnets. These include common metals such as copper, aluminum and brass. eg. non-magnetic substances are wood, glass, copper plastic and rubber
The Difference Between The Two Poles Is Basically The Magnetic Force Between Them That Pushes Eachother Away. ?
A magnetic field is generated when electric charge carriers such as electrons move through space or within an electrical conductor.
In relation to aviation... Deviation is the difference between a true heading and the compass heading. The compass heading is different from true due to magnetic fields induced by the components of the aircraft. Variation is the difference (angle) between True North and Magnetic North. Variation changes depending on your position and is normally indicated on maps as a dashed line with the variation in degrees along that particular line.
Pole strength is ability of poles to produce lines of force where is field strength is force which a magnetic poles experiences when places in magnetic field.
Magnetic field intensity speaks of the strength of a magnetic field, usually in Tesla, whereas forces deal with units of Newtons and are fundamentally characterized through F=MA in conjunction with Newton's Laws.
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!!! ; )
When magnetic material is kept in a magnetic field then it experiences a force. when nonmagnetic material is placed then there is no force acting on it. If you know, the origin of magnetism, you will find that when the electrons of any substance cancel the total charge of each other(produced by their spinning and moving around the nucleus) then that sub. is non-magnetic.
No difference - a cassette contains magnetic tape.
magnetic variation
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 declination or variation.
Electric Current I= V/R where V is volts and R is resistance; Magnetic Current I=Hw where H is the Magnetic Intensity and w is the wave distance.
A magnetic material will become non-magnetic if the temperature is increased beyond its magnetic transition temperature. For example, iron will be non-magnetic if its temperature exceeds about 1050 kelvin. Transition temperatures for different magnetic materials vary over a wide range. The element Gadolinium has a transition temperature near room temperature. Many other materials must be cooled to close to absolute zero in order to be magnetic.Another way to make a magnetic material non-magnetic, which may be possible for some materials, is to add an appropriate quantity of impurities. For example most stainless steels are non-magnetic even though they are mostly iron.It is also important to recognize the difference between magnetic materials and magnetized materials. Magnetic materials can be demagnetized, so they do not act like magnets, even below their transition temperature. They are still magnetic, but the magnetic regions within the material, called "domains," have been randomized in direction. When the material is magnetized, those internal fields tend to line up and combine their strength. Magnetizing and demagnetizing is often confused with magnetic and non-magnetic transitions, however the two phenomena are quite different in nature.
