Electromagnetic waves have a variety of uses depending on wavelength. In decreasing lengths, classifications are Radio, Microwave, Infrared Light, Visible Light, Ultraviolet Light, X-ray and Gamma ray waves.
Radio waves are commonly used for wireless communication, since they are largely harmless.
Microwaves are at the wavelength needed to excite a specific element common in edible substances (I believe it's hydrogen, but I could be wrong). This makes that part of the Microwave range useful in heating edible substances, and is used in commercial microwaves, via the part therein known as the Magnetron.
Infrared light is largely unexploited, as it is emitted by most objects at room temperature. This results in far too much noise to be useful in most uses, but does allow for infrared sensitive cameras to see in the dark. This is most commonly useful in military applications, as it allows soldiers to see in the dark without subjecting them to the issues of light intensity changes with light amplification equipment like night vision goggles.
Visible light is, by definition, the class of wavelengths visible in the human eye. Its uses are too numerous to name
Ultraviolet light is harmful to humans (sunburns, etc), but does have a number of uses, according to wikipedia's article (the numbers refer to wavelengths, 1nm is 1/1000000000 of a metre (or 3.28 feet):
X-rays are used for density scanning equipment. Examples include security systems like those found in most airports for scanning baggage and in medical diagnosis of a wide array of problems. While potentially very harmful to humans in sufficient dosages, they are still useful since they provide a clear image of the human skeleton, enabling easy detection of bone breaks or fractures, and certain other problems are also clearly seen (Tuberculosis, for instance, creates an abnormally dark shadow in the lungs). Interpretation should be left to a medical professional. The image is far less detailed than that produced by CT or MRI scanning, but is far simpler to use and more widely available.
Gamma rays are extremely hazardous to life in general and exceedingly rare. They are the byproducts in nuclear reactors, which necessitates extensive shielding of the reactor core (where fission actually occurs) to protect people nearby (one can be leaning against the reactor shielding and still be several tens of feet from the core itself). They are the primary method of killing a large number of cells very quickly. The only case I know of where this method is commonly used is in cancer curatives - once a cancerous region is identified, low intensity gamma rays are injected to the region from a variety of angles - the total exposure to healty tissue remains below safe limits, but the exposure of the cancerous cells to gamma rays is sufficient to cause destruction. It is an alternative to chemotherapy or surgery. All three methods are exceedingly bad for the entire human body, which is one of the major problems with curent cancer treatment: the "cure" is almost as bad as the cancer is.
An electromagnetic battery works by converting mechanical energy into electrical energy through the movement of a magnet within a coil of wire. This process generates an electric current that can be stored and used to power devices. The advantages of electromagnetic batteries over traditional batteries include faster charging times, longer lifespan, and higher energy efficiency. Additionally, electromagnetic batteries are more environmentally friendly as they do not rely on toxic chemicals like traditional batteries do.
Speed: Electromagnetic waves travel at the speed of light, making them extremely fast for transmitting information. Long range: Electromagnetic waves can propagate over long distances without the need for a physical medium, allowing for wireless communication. Versatility: Electromagnetic waves can be easily modulated for different applications such as radio communication, radar, and medical imaging.
The advantages of using a fiber optic sheet in communication technology include faster data transmission speeds, higher bandwidth capacity, greater reliability, and resistance to electromagnetic interference.
Optical fibers offer advantages such as low signal loss over long distances, high bandwidth for data transmission, resistance to electromagnetic interference, and security due to difficulty in tapping the signal without detection.
An electromagnetic train, also known as a maglev train, works by using magnetic levitation to lift and propel the train along a guideway without the need for wheels. This technology allows for faster speeds, smoother rides, and lower maintenance costs compared to traditional trains that rely on friction between wheels and tracks. The main advantages of electromagnetic trains include reduced noise, increased energy efficiency, and higher speeds, making them a more sustainable and efficient mode of transportation.
Being able to turn electromagnetic on and off is what separates it from a normal magnet.
Key Advantages as follows:1. immunity to electromagnetic interference. EMI2.. High data rates3. Long maximum distances4. Better security

Electromagnetism is an efficient way in which to turn a motor. It does not produce pollution and it is otherwise environmentally safe.
Advantages... Compared to what? This law is one aspect of how our world works; it isn't something we can turn on or off.It is essential to the operation of transformers, motors, generators. There are also situations in which it can be a nuisance.
