yes
no there is no use of electromagnets in iron box
CAT Scan does not use electromagnets, its MRI (Magnetic Resonance Imaging) which uses Electromagnets to produce images of the patient's body.
no
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.
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.
Electromagnets are used in many ways. Televisions use electromagnets to direct the electron beam, whereas loudspeakers and earphones use electromagnets to push the diaphragm forwards.
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
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.
MRI machines use powerful electromagnets to produce detailed images of the inside of the body. Electric door locks use electromagnets to secure doors when electric current is applied. Maglev trains use electromagnets to achieve high speeds by levitating above the tracks without friction. Speakers use electromagnets to convert electrical signals into sound waves.
Yes, phones use electromagnets in various components such as speakers and vibration motors. Electromagnets are used to convert electrical signals into sound waves in speakers and create vibrations for notifications in vibration motors.
Two common devices that use electromagnets are electric motors and loudspeakers. Electric motors use electromagnets to generate movement by converting electrical energy into kinetic energy, while loudspeakers use electromagnets to convert electrical signals into sound waves.
Most vacuum cleaners do not use electromagnets. They typically rely on an electric motor to create suction for cleaning. Electromagnets are typically used in applications like speakers, doorbells, and MRI machines.
