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 magnet is magnetic because it is a "permanent" magnet. An electromagnet is a magnetic field caused by a current flowing through a wire.
If your refrigerator is outside in -10 degree Celsius weather I find that the refrigerator is unnecessary. If you do decide to still use the refrigerator outside make sure your refrigerator has a power source so that it can keep running.
Not generally, although MacGuyver could make an electromagnet with a toothpick and a spool of wire.
A choke, an electromagnet, an electric motor stator, an electric motor rotor, etc. all depending on details of construction and use that are unstated in the question.

He wound wire around it to make a tranformer.
IT is different because an electromagnet runs with electricity. A refrigiator does not run with electricity.
u need 2 provide more information"Which of these materials would be best to use for the core in order to make the strongest electromagnet to?"u need to provide what "these materials" are
how to make road rail signal using electromagnet
This question does not make sense in the slightest.
electromagnetically
yes. but it also wastes energy as sound
yes it does
No.
Put it in a sealed container and put it in the refrigerator.
