What has the author Herbert H Woodson written?
Herbert H. Woodson has written: 'Electromechanical dynamics' -- subject(s): Dynamics, Electromagnetic devices, Electromagnetism, Electromechanical devices
What kind of energy does an electromagnet use?
electromagnetism
What is the relation between medical and electromagnetic?
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.

What are some future applications of Electromagnetism?
Balls.
What are the physical examples of electromagnetism?
Some trains uses electromagnetism to move along metal tracks. I think some other transportation vehicles do also.
What are some examples of an attractive force?
Electromagnetism Gravity
What are some applications of electromagnetism?
Electromagnetism has created many changes in the fields of engineering, space, medicine, and more. One of the more ubiquitous uses of electromagnetism is its ability to allow us to simply switch electricity on and off as needed.
What is electromagnetism used for?
Electromagnetism is one of the four fundamental forces, the other three being the Strong Atomic Force, the Weak Atomic Force, and Gravity. Electromagnetism is used for nearly everything we do involving power, motors, nerves, and chemistry, just to name a few.
How electromagnetism generates rotary movement?
if a component has an electrical connection and movement is created by or within the component, then that component will use an electromagnet. Devices such as relays, solenoids and motors, use electromagnets to create movement. Ignition coils and transformers use electromagnetic induction to raise or lower voltage outputs
How do electric and magnetic field interact in an electromagnetic wave?
They both use electromagnetism.
What devices use a LDR?
some outdoor timers for lights
