electromagnetic devices are devices that work on electricity but are magnetic
your cellular phone -- it converts EM signals into audible signals and back.
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
It depends on the type of interference, but most shielded cables are used in a copper cable setup. You could also use fiber optic cable if concerned about electrical devices but it might prove too expensive.
On some platforms (unix, for example) devices are handled as special files.
Some actuator or devices are operated by compressed air. These devices are known as pneumatic components
I'm working on a science project where I need some form of artificial electromagnetic energy. I've heard that a coil produces some radiation but I don't know much about electronics and need an easy way to create some ER.
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.
The answer is iron.
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
Infrared waves from the electromagnetic spectrum are used in heat lamps and heat sensing devices.
Some people believe that electromagnetic radiation from power lines and electric devices can impact human health. This is largely unproven.
noise
maser : any of several devices that amplify or generate electromagnetic waves, especially microwaves.
No.

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.
