Electromagnetic energy is an invisible form of energy in the transverse wave form. Of the many types of energy in our universe, this form of energy is the only one that does not require a medium or matter to travel on or in. This form of energy can travel through empty space as a transverse wave. There are many different types of electromagnetic energy. Examples of Electromagnetic Energy: 1. Radio waves 2. Microwaves 3. Infrared radiation 4. Visible light - all colors of the spectrum that we can see. 5. Ultraviolet light 6. X-rays 7. Gamma radiation
What else can I help you with?
Why electromagnet is different from a permanent magnet because an electromagnet what?
Mainly in that the electromagnet is NOT permanent. In other words, it can be switched on and off.Another relevant difference is that the electromagnet constantly requires power, at least while it is on.
How do you turn off an electromagnet?
This is what makes a magnet an electromagnet - the ability to turn it on and off... Anyway, electromagnets can be turned off with either the help of a switch, or just by disconnecting the power supply.
The strength of an electromagnet only depends on the current in the coils?
And the amount of coils.
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
How can an electromagnet be made stronger?
An electromagnet can be made stronger by: - A bigger iron rod. - A bigger battery/more batteries - More coils around the iron rod. - A bigger magnet. - Increase the current flowing through the coil. - Put in a soft iron core.
Which is better a permanent magnet or an electromagnet?
electromagnet
What does an electromagnet operator do to release metal attached to the electromagnet?
An electromagnet operator can release metal attached to the electromagnet by turning off the electric current flowing through the electromagnet coils. This de-energizes the electromagnet, causing the magnetic field to dissipate and the metal object to fall off.
An electromagnet becomes storgner when the?

What is an example of a sentence using the word electromagnet?
Electromagnets are widely used now. Instead of traditional magnets.
Who built the first electromagnet?
Linc Robinson built the first electromagnet.
When was the electromagnet invented?
The electromagnet was invented in the year 1850 by william sturgeon :)
What is the difference between electromagnetism and electromagnet?
electromagnetism is the force an electromagnet is the object
An advantage of an electromagnet (in contrast to a bar magnet) is?
An electromagnet can be turned on and off.
