Inductor, rodin, and deflection are some types of electromagnetic coils.

no
The most common tattoo machines in use are electromagnetic
Sonar navigation uses sound waves; radar navigation uses electromagnetic waves (usually radio eaves).
Inductor, rodin, and deflection are some types of electromagnetic coils.
Increasing the coils will increase the strength of the magnetic field.
The principle of Electromagnetic Induction
A toaster takes in electricity from some power source, then it uses this electricity to heat coils within the toaster. The coils get very hot, and emit heat in the form of electromagnetic radiation (light). The bread/bagel/sock that you put into the toaster absorbs this radiation and gets hot.
One variable that needs to be controlled is the number of coils of the electromagnet as the more coils the stronger the magnetic force, so the same number of coils should be used for each test.
field coils generally refer to the electromagnetic coils on the stator ( the stationary part of an electric motor ). these generate the magnetic field(s) necessary to put the rotor ( the rotating part of the motor ) into motion.
They normal clutch mechanism but driven by electromagnetic solinoid coils. They are used where the motors are to be engaged and disengaged during running, with out stopping the operation.

A transformer
we use electromagnetic waves in radios and cell phones
The radio frequency portion of the electromagnetic spectrum uses radio telescopes.
It is not at all clear what you mean by locating the electromagnetic spectrum. Electromagnetism exists at innumerable locations throughout the universe. Vision is a sense that uses a part of the electromagnetic spectrum, and lots of animals can see. Some animals, such as bees, can see in ultraviolet frequencies that the human eye does not see.
