What are 10 uses of magnets in our daily life?
Magnets are used to make a tight seal on the doors to refrigerators and freezers. They power speakers in stereos, earphones, and televisions. Magnets are used to store data in computers, and are important in scanning machines called MRIs (magnetic resonance imagers), which doctors use to look inside people’s bodies.
How do headphones use electromagnets?
The motor effect is used inside headphones, which contain small loudspeakers. In these devices, variations in an electric current cause variations in the magnetic field produced by an electromagnet. This causes a cone to move, which creates pressure variations in the air and forms sound waves.
Do cars use magnets?
Magnets are used in various aspects of building a car, from the production line through to the finished product. To hold parts in place during production, manufacturers will install heavy duty magnets to lift heavy components of the vehicle, including the outer shell and doors.
