Some examples of objects that do not use electromagnets include simple tools like hammers, nails, or screws, as well as natural objects like rocks, trees, and animals. Additionally, non-electronic kitchen utensils such as knives, cutting boards, and plates also do not rely on electromagnets.

What are two common objects which contain electromagnets?
Two common objects that contain electromagnets are speakers and electric door locks. Speakers use electromagnets to convert electrical signals into sound waves, while electric door locks use electromagnets to control the locking mechanism.
What are the objects that use electromagnets?
Speakers! All speakers are is a magnet on the back of a cup to push air. More complex than that, but its a general jist of it. An alternator in a car is another one. Check out http://en.wikipedia.org/wiki/Electromagnets#Uses_of_electromagnets for a good list.
Do fans use electromagnets?
Yes, some fans use electromagnets in their motors to generate the magnetic field needed for rotation. These electromagnets are energized by an electrical current to produce the desired magnetic force.
What are some items that use electromagnets?
Some common items that use electromagnets include electric motors, MRI machines, speakers, and relays. Electromagnets are also used in various electronic devices such as doorbells, computer hard drives, and magnetic locks.
What objects use electromagnets?

What are electromagnets used to record information on?
Electromagnets...electromagnets are magnets attract, or pull, some kinds of metal objects. Stronger magnets exert a greater pull on the objects they attract. Sometimes it would be useful if you could turn off a magnet when you did not want it to attract objects. That is what an electromagnet can do. Some electromagnets .in power plants and factories electromagnets are very large. You can make a small, simple electromagnet in school or at home.
