Aside from cute magnets for sticking photos on your fridge, can you find all the other ways you can use magnets like heavy duty mounting magnets in your home?

1. Microwave magnets: Microwaves use magnetrons composed of magnets to generate electromagnetic waves that heat food.

2. Refrigerator door: The refrigerator and freezer are sealed with a magnetic mechanism, so it is easy to close tightly.

3. Spice rack: Magnetic spice racks with neodymium magnets are easy to make and help clear up valuable counter space.

3. Handbags and jewelry: The buttons of handbags are usually equipped with magnets. Magnetic clasps are also used to make jewelry.

4. TVs: All TVs have cathode ray tubes or CRTs, which have magnets in them. In fact, TVs exclusively use electromagnets to direct the flow of energy to the corners, sides and halves of the TV screen.

5. Doorbell: It's not exactly in the bedroom, but the doorbell has magnets, it may have several, you just need to listen to the number of tones it produces. The bell also contains a solenoid, which causes a spring-loaded piston to strike the bell. It happens twice because when you release the button, the magnet goes under the piston and hits it.

Ⅲ. Magnets in the office

1. Cabinets: Many cabinet doors are secured with magnetic latches so they won't open accidentally.

2. Computer: Magnetism is the main component of the computer. Hard disk drives have disks coated with tiny magnets that allow the computer to store data.

3. Organize office supplies: The neodymium magnet rust helps to organize. Metal office supplies like paper clips and thumbtacks stick to the magnets so they don't get misplaced.

Ⅳ. The magnet in the speaker

Most speakers are made of some sort of permanent magnet that interacts with a coil (actually an electromagnet). The audio signal flows through the wires, moving the speakers. The speaker moves the air, making the sound.

How many speakers are in a home? Count all speakers: don't forget radios, stereos, TVs, etc. Count the phone speakers, not the microphone. (Most cell phone microphones are condenser/electret microphones and do not contain permanent magnets.) Don't forget the speakers in your car. Count every earbud in any music playback device you might own.

Which use neodymium magnets? Usually it's those where small size matters. While a subwoofer's giant speaker might use ceramic magnets, the tiny earbuds you use with your smartphone or MP3 player might use neodymium magnets.
