Our Professor said there will be still an electric field in empty space even without charges.Hows that possible.Space-time has a some quantum property that acts like this ?
He said aomething like this.Theres electric fields or some field and ıf charge comes there like a postive one It disturbs the field.And makes our normal things it was something like that I don't quite remembermfb said:If there are no charges at all in the whole universe, there won't be an electric field. But there are charges in the universe. You have an electric field even in regions without charges due to charges elsewhere.
Dale said:You may have misunderstood your instructor. I would ask him or her for clarification directly.
Make sense then...So ıf there's no charge in space-time its just there but "mathematically"mfb said:Well, technically "the electric field" is defined everywhere in space even without charges. Its strength is zero in that case. Usually this is called "no field", although mathematically the field is there.
mfb said:If we have charges somewhere, the value of the field becomes non-zero.
A field that is zero everywhere doesn't do anything, at least in classical physics.
An electromagnetic field in empty space is a physical field that is created by the presence of electrically charged particles. It consists of electric and magnetic components, which are perpendicular to each other and oscillate at right angles to the direction of energy flow.
An electromagnetic field in empty space plays a crucial role in the transmission of energy and information. It is the medium through which electromagnetic waves, such as light, radio waves, and microwaves, travel through space at the speed of light.
An electromagnetic field in empty space is measured in terms of its electric and magnetic field strengths. These can be quantified using specialized instruments such as voltmeters and magnetometers.
An electromagnetic field in empty space is directly related to the electromagnetic spectrum, which is a continuum of all possible frequencies of electromagnetic radiation. The strength and frequency of the field determine the type of electromagnetic radiation emitted, such as visible light or radio waves.
Yes, an electromagnetic field in empty space can be manipulated through the use of electric and magnetic fields, as well as through the use of materials with specific electromagnetic properties. This manipulation can be used for various purposes, such as communication, energy transmission, and medical imaging.
