Name Electromagnetic Technologies

[MattsVai]

Hi all,

Examples of electromagnetic tecnologies that I am familiar with are particle accelerators, maglev trains, and mass spectrometers... however, I am curious as to what other tecnologies currently exist that involve electromagnetism. Thanks!

Cheers,

Matts

Automobile speedometers. (And everything else that has wires. Just as a starting point..)

Sounds like a nicely phrased homework question!

Anything that has wires or a circuit board or produces light, pretty much.

Hahaha! Nice try MK ;) Actually this question arose from me DOING my homework on particle accelerators. Now I am just curious about other technologies.

Anything with a circuitboard is more electronics with a small component of electromagnetism isn't it?

Is this all we have in the form of forefront electromagnetic technologies?

"Electromagnetic"
-wireless data and power transmission.
-satellities, or infact any device using the EM spectrum (including all light devices). :)
- Giant, efficient generators and motors.
- Small, powerful, precise robotic motor actuators
- hundreds of types of sensing
- i.e. medical imaging, X-Rays
- radar, remote sensing

Come on.

Almost all cool technologies are electromagnetic.

(Almost...) everything we perceive on this planet, apart from the force holding us down, is electromagnetism. Condensed matter interacts almost entirely through electromagnetic effects - all except the exotic stuff that nobody was even aware existed a hundred years ago.
