Can you create vacuum with the help of electric and magnetic fields?

Normally you create vacuum by pumping out the air from a sealed container. Electric and magnetic fields would seldom be used, unless you had some electrically charged particles that you wanted to remove from your partial vacuum.

Why is light in the electromagnetic spectrum Is light a type of electromagnetic radiation But how does that work Light is not magnetic or is it?
Part of the electromagnetic spectrum can be detected by eye, and we call that bit "light". The thing about electromagnetic radiation is that a varying magnetic field causes a (varying) electric field (that's how power stations make electric current) and a varying electric field causes a (varying) magnetic field. So electromagnetic radiation is what you get when a varying electric field creates a varying magnetic field which in turn contributes the varying electric field. The whole thing then appears as bundled varying electric and magnetic field wave system which propagates at the velocity of light, That is why it is called electromagnetic. There are no magnetic poles or electric charges in it, and it can travel through a vacuum.
Is there a difference between empty space and an absolute vacuum ie Does an absolute vacuum posses a Higg's field?
THEORETICALLY: An absolute vacuum has no mass contained. In empty space there is no mass, so an absolute vacuum is empty space and empty space is an absolute vacuum. There is no difference. Although, there may be energy passing through the empty space or vacuum in the form of electromagnetic waves, or gravitational or magnetic fields.
Can macnetic waves travel at the speed of ligth?
Light is an electromagnetic wave. Electromagnetic waves travel at the speed of light. Electric and magnetic waves don't travel on their own - the wave travels as a combined electric and magnetic wave.
How are electromagnetic waves transmitted and received?
This is done by microwave antennas,since signals can be sent in form of waves.Those types of waves are commonly known as electromagnetic waves i.e waves that result due to the electric and magnetic fields.
Will electromagnet can work in space?
Magnets work because their atoms are aligned in certain orientation so that the magnetic field is not chaos but is organized as ripples around the matter. Such organized electromagnetic field of any nature can exist without any supporting media like air or water. If you think space is vacuum then you are wrong again. There is a lot of black or dark matter (invisible to current scientific equipment) in this universe and lots of particles like cosmic rays emitted by stars and galaxies. So magnets will work regardless of vacuum or space.
Can magnetic fields travel in vacuum?
Yes
Diffrene between electro magnetic and mechanical waves?
An electromagnetic wave is a disturbance, which does not require any material medium for its propagation and can travel even through vacuum. They are caused due to varying electric and magnetic fields. Radio waves and light waves are examples for elect..These are waves that can pass through vacuum in addition to passing through matter. In other words, a material medium is not necessary for their propagation. They consist of periodic variations of electric and magnetic fields at right angles to each other and also at right angles
Why do EM waves not require a medium?
Both electrostatic fields and magnetic fields can influence objects in a vacuum, so EM waves (the combination of varying electromagnetic and electrostatic fields) have influence through a vacuum, that is, in the absence of a physical medium.
How electromagnetic waves travel in a vacuum?
Electromagnetic waves are changes in both the electric and magnetic fields of space, which propagate as a wave. These do not need atoms to propagate - on the contrary, the presence of matter tends to interfere with light, etc.
What happens when white light passes through a strong magnetic field?
I have the impression that light is not affected by magnetic fields - at least in a vacuum. If traveling through other substances, the magnetic field can change the light's polarization.
What may be said about the electric and magnetic fields of a proton moving through space if it does so without any change in its velocity?
If a proton is moving through space without any change in its velocity, then its electric and magnetic fields are not interacting with any other electromagnetic fields. There are no other fields present, and about the only place where a proton can move without interference is deep space. There will still be some electromagnetic radiation, even there. And this will have an effect on the protons's fields. There may also be another charged particle or two about as well. In reality, there is no place that is completely free of electromagnetic fields. But if there were, it would be a perfect vacuum with no light or any other electromagnetic radiation moving through it.
Why are electrons in a cathode ray tube deflected by magnetic and electric fields?
By nature electrons are charged particles (with a -1 charge). Also there's an established relationship between electricity, which involves the flow of electrons, and magnetism, known as electromagnetism. Ampere's right-hand rule suggests the magnetic field moves in a corkscrew direction perpendicularly in reference to the direction of the flow of electrons (electrical current).
What technologies come from magentic fields?
Magnetic Levitation (MagLev) trains, hard disk drives for computers, vacuum cleaners, and several others
How do you create a vacuum cleaner that runs on clean energy?
Use an antique hand pumped vacuum cleaner (they existed before the electric ones).
Do magnets attract and repell in outer space?
Yes! It should. Since the magnets, irrespective of external magnetic fields, have their own magnetic field. Vacuum or Air pressure, quality, etc also don't effect the magnetic fields of magnets. Hence, depending on Negative or Positive side of the magnets, when brought together, it will attract or repel accordingly!!
What is the force of attaraction between two objects in a vacuum?
The force will always be gravitational. In addition we might have magnetic force, and electric force.?Regards.
How do waves travel through vacuum as wave is a disturbance caused in the particles and vacuum does not have any particles?
The vacuum has an "Ether" with z=375 Ohms and it has electric and magnetic charge z=W/Q where W is the vacuum magnetic "charge" in Webers and Q is the Electric charge in Coulombs. Z is related to Planck's Constant h= WQ.Q= 4/3 E-18 Coulombs and W= 500 E-18 Webers.The electromagnetic wave "disturbs" the ether medium.
