Electromagnetic energy comes from something that is positively charged... like a fully functioning device such as a full spectrum camera or very powerful electrical outlets.
A battery changes chemical energy into electric (electromagnetic) energy.
Uranium powered 9 volt battery glued to a magnet.
If it has a battery that is electromagnetic energy, but if you mean radiation force you need 300 megawatts of power for 1 Newton force.
electromagnetic energy?
In a compressed air tool the driving force is air pressure. While in battery tools the electricity from the battery is converted to electromagnetic force to drive it.
you dont, just take a nail and a wire and put it together with a battery.
by taking a nail and rap it around the nail and then something metal after get a battery and a switch
battery ---> light bulb chemical energy ---> electromagnetic energy (heat and light)
You get a battery, switch, nail and copper wire. You connect one end of the battery to the switch and the other end to the nail that is wrapped with some copper wire. The end of the switch that isn't connected you connect to the electromagnet.
It depends what you are talking about... Electromagnetic field Electromagnetic force Electromagnetic radiation Electromagnetic spectrum Electromagnetic therapy Electromagnetic waves ...they each have different meanings.
Electromagnetic waves are transferred by electromagnetic radiation.
the principle on which an electromagnetic crane works is electromagnetic induction
