yes it does
No- but if it has an electric motor (most do) the motor operates by use of an electromagnet. Many refrigerator door seals (not all) includes magnets.
A refrigerator is not a magnet, however it does contain an electric motor, and within that motor are permanent magnets (as well as electromagnets).
You use electricity every time you use a light-bulb, a computer, an electric stove, a refrigerator, etc. You use magnetism (as well as electricity) every time you use an electric motor, or a loudspeaker. For example, the motor in electric toys, in a refrigerator, or in a hair drier.
