A refrigerator is not a magnet, however it does contain an electric motor, and within that motor are permanent magnets (as well as electromagnets).

How does magnetic car sign work?
A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets. A refrigerator magnet is an ornament attached to a magnet that is used to post items such as shopping lists or report cards on a refrigerator, or simply as decoration. Refrigerator magnets come in a wide variety of shapes and sizes, including for example, images die-cut to a specific shape or tiny plastic sculptures of fruits. Refrigerator magnets are a relatively popular object of collectors.
What is an example of magnetic field?
The atmosphere of the earth is a magnetic filed
Explain How electricity is derived from a magnet?
When any material moves through a magnetic field (for example, close to a magnet), a voltage is induced in the material. If the material is a good conductor, and is properly connected, a current can be derived from this. Moving the conductor through the magnetic field requires work (due to the magnetic field of the moving conductor itself); thus, mechanical energy is converted into electrical energy, and energy conservation is not violated.
What is the steps of making magnetic materials to non magnetic materials?
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.
How does ferromagnetic apply to permanent magnets?
A permanent magnet is an object made from a material that is magnetized and creates its own persistent magnetic field. An everyday example is a refrigerator magnet used to hold notes on a refrigerator door. Materials that can be magnetized, which are also the ones that are strongly attracted to a magnet, are called ferromagnetic (or ferrimagnetic). These include iron, nickel, cobalt, some alloys of rare earth metals, and some naturally occurring minerals such as lodestone.
What is a piece of magnetic material that remains its magnetic proporties after it is removed form a magnetic field?
Many materials which are capable of being effected by a magnetic field will retain some of those properties once its no longer in direct contact with the field. One example is iron. It can become magnetized by being introduced to a magnetic field and then continue to remain magnetic once the source field is removed.
What is the difference between magnetic metal and nonmagnetic metal?
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.
Is a refrigerator an example of a conductor?
no
Name a magnetic material?
exmaples of magnetic materials are iron,nickel,cobalt,paper clips,nails and some pins....:-)Example (A Science Trick):COINS=CO-BALTI-RONN-ICKLES-TEEL
Is sheet metal magnetic?
Not necessarily; tin is not magnetic, for example.
