There are many uses for permanent magnets and temporary magnets like an electromagnet. Electric appliances with electric motors use magnets to turn electricity into motion. Other examples include electric toothbrushes, fans, lawnmowers, and anything else containing a motor.
Magnets are used to hold doors closed, such as in refrigerators, kitchen cabinets and others. Magnets are also used to read and write data on a computer's hard drive or on old-fashioned cassette tapes. There are more magnets in headphones and stereo speakers which help to turn stored music back into the sounds you can hear.
In summary, magnetism is another property of some kinds of matter. There are two poles to a magnet, the south pole and the north pole. Like poles repel and unlike poles repel. There are two different kinds of magnets, temporary and permanent. A temporary magnet can be made by using electricity. All magnets contain an invisible electromagnetic field which surrounds the magnet. There are many uses for magnets, from holding doors closed to helping music sound better with the magnets inside of speakers.
Based on the information provided above how would you describe a magnet?
Answers
Answer:
A magnet is a piece of metal with a strong attraction to another metal object. The attraction a magnet produces is called 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, such as iron, steel, nickel, cobalt, and so on. and attracts or repels other magnets.
Most magnets are made of iron, and magnets are used in many common items like cassette tapes, credit cards, toys, and compasses. Magnets are used to make a tight seal on the doors to refrigerators and freezers.

The Sun
Explanation:
It is the major source of energy for organisms and the ecosystems of which they are a part. Producers, such as plants and algae, use energy from sunlight to make food energy by combining carbon dioxide and water to form organic matter. This process begins the flow of energy through almost all food webs.

What does latitude have to do with the prevailing westerlies?
Answers
Answer:
The westerlies, anti-trades, or prevailing westerlies, are prevailing winds from the west toward the east in the middle latitudes between 30 and 60 degrees latitude.
Explanation:
Prevailing Westerlies are the winds in the middle latitudes between 35 and 65 degrees latitude. ... This creates frictional or drag in the motion which ultimately slows the Westerlies down. The strongest westerly winds in the middle latitudes can come in the Roaring Forties which is between 40 and 50 degrees latitude.
