An electromagnetic device is any device that uses electromagnets to operate. Some examples include: electric motors, electric generators (alternators), speakers, etc. An electromagnet is typically a coil of wire with an electric current running through it which generates a magnetic field according to laws and principles developed by Ampere, Faraday, and Maxwell among others. Electromagnetism was discovered by Oersted in 1820.
electromagnetic devices are devices that work on electricity but are magnetic
Cell phones are electromagnetic devices. This is because they use electromagnetic radiation to emit radio-frequency energy when interacting other electronic devices.
electric bells cranes
The answer is iron.
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
loudspeakers, tape recorders,motors,etc.
Nearly all electrical devices will emit some electromagnetic radiation. In some cases this can be strong enough to affect nearby sensitive instruments or radio receivers and can be the result of multiple devices operating in a small area.
Motors, solenoids, lifting devices. (doorbells, electric razors, junk yards)

maser : any of several devices that amplify or generate electromagnetic waves, especially microwaves.
UV waves are caused by the electromagnetic spectrum that imitates the sun. It is used in heat lamps and sensing devices.
There is no relation between medical uses of electromagnetic energy and alternative devices. There are no available scientific evidence to support claims in treating any diseases with the use of electromagnetism.

The (electromagnetic ) radiation they emit is short or micro wavelength ( 2.45 GHz frequency) which causes resonance in water molecules, resulting in rapid heating.

Electromagnets are widely used in the society. An advantage is that humans use electromagnets in all kinds of useful utensils like doorbells, telephones, cranes, computer disks, mobile phones, televisions and so on. Also eye surgeons, while performing operations, use electromagnetic devices to recover the patient.

There are many interesting devices. A spectrophotometer is an instrument made to measure properties of light over a specified area of the electromagnetic spectrum.
