No.
It's more like a cathode ray tube.
No.
It is used in UV lamps, paint testes, projection lamps, electronic flashes, xenon arc lamps etc. It is also used in photography and as a general anaesthetic.
Modern table lamps use all sorts of different light bulbs. Most commonly one can find standard 20 watt to 250 watt light bulbs in modern table lamps.
things like tosters, microvaves, fridge, freezer and so on ..............
Probably. They don't use real lava.
That one type of salt that people use with lava lamps
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 are used in various applications such as MRI machines in the medical field, speakers and headphones in audio devices, and electric motors and generators in industrial machinery. They are also used in magnetic levitation trains, particle accelerators, and in various electronic devices like relays and solenoids.
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.
yes
Electromagnets are used in scrap metal yards to pick up and move large pieces of metal. They are used in MRI machines to produce detailed images of the body. Electromagnets are used in cranes to lift and move heavy objects. They are used in speakers and headphones to convert electrical signals into sound waves.
The ancient Greeks understood magnets but since they did not have a source of electricity, they did not use electromagnets. They did make compasses.
Yes, compasses use a magnetic needle that aligns with the Earth's magnetic field. The needle itself is not an electromagnet, but it relies on the Earth's magnetic field to point towards the magnetic north pole.
Electromagnets are used in a range of industries, including manufacturing, transportation, healthcare, and energy. They are commonly found in electronics, automotive applications, MRI machines, and electric generators.
Cranes use electromagnets because they can be controlled and turned on/off easily by adjusting the electric current. This provides flexibility in lifting and releasing materials. Permanent magnets, on the other hand, have a fixed magnetic strength and cannot be adjusted or controlled.
Surely you jest.
