What happens when a atomic bomb explodes?
When an atomic bomb explodes it forms a mushroom cloud, the explosion gives off EMP or Electro Magnetic Pulse, the explosion is huge and can destroy so much for miles, and the explosion gives off huge amounts of radiation so if you survive the explosion you can suffer or die from the radiation after the bomb blew up.
The electromagnetic waves with the highest energy are?
Gamma rays--powerful enough to melt your face off. Ouch. The Earth's electro-magnetic shield, generated by a molten, spinning magnetic core, can protect us from most of the sun's radiation, but it draws the line at gamma rays.
The loss of static electricity as a charge move off an object?
The loss of static electricity as a charge moves off an object is known as an electro static discharge.
Whyb are natural magnets noy used in cranes to lift heavy loads?
The electro-magnet can be switched on and pick up metal. Then the electro-magnet can be switched off and the metal will be released. A natural magnet would not release the metal.
What two forms of energy that resistors can give off?
Heat energy as radiant heat Light energy if the resistor gets hot enough it will glow Sound energy, some resistors will hum at certain voltages Magnetic, electricity travelling through a wire will induce a magnetic field.
What type of energy does a black light give off?
Optical energy electro-magnetic energy in the UV-section of the spectrum radiated energy
Do sunspots give off magnetic rays?
Sunspots do give off magnetic rays.
Why do stars give off electromagnet radiation?
they are magnetic
What kind of force does a magnent give off?
Magnet* does*, and i gives off magnetic energy.
How are the energy and wavelength of electro magnetic radiation related?
The Relationship is the 'Flux' of the magnetic field.Changing the amount of energy will not effect the wavelength (except to choke off the field when it becomes too dense)and increasing the wavelength will increase the energy density (flux)
What is relay driver?
A relay is an electro-magnetic switch which is useful if you want to use a low voltage circuit to switch on and off a light bulb (or anything else) connected to the 220v mains supply.
What magnet can be switched on and off?
An electro-magnet can be turned on and off.
Why are hard magnetic materials used to make electromagnets?
Hard in this sense means materials that are themselves not easily magnetised. In fact, the part that you are referring to isn't really the magnet - it is the core, the magnetic field is produced by the coil, the core just concentrates the field. In an electro-magnet, the core must retain little or no field when the coils are not excited/energised. This means that items picked-up/attracted by the electro-magnet are no longer attracted when the coil is denergised - you can unload/drop the load from your crane or hoist by switching off the electro-magnet.
What type of energy does a portable CD player give off?
kinetic. Possibly minute magnetic.
What gives off electromagnetic radiation?
Many things give off electromagnetic radiation. Cell phones, the body, x-rays, and supposedly ghosts and spirits. EMF detectors (or electro-magnetic-field detector) are also supposed to pick up electromagnetic radiation given off by anything it's pointed at.
What is electromagnetic crane?
it is a crane no its an electro magnetic crane An eletromagnetic crane is a crane that has a giant magnet to pick up things with cobalt, nickel or iron in them. The magnet is run through electricity so you can turn it on and off at will.
Why does fire give off light?
I was actually looking into this myself and this is what I've gathered. Fire is basically the releasing of molecules such as carbon which then combine with oxygen to form a complete pair. This process releases energy , which "excites nearby electrons" which then give of electro magnetic energy to which the light waves are channeled through the eye to hit the retina which give us the image of light. Correct me if I'm wrong but that is what I have gathered thus far.
