Does electric motors change mechanical energy to magnetic energy?
Electrical energy in the form of electric current passing in the vicinity of magnetic field would create a mechanical rotation in the coil. So conversion of electrical into magnetic energy. Magnetic interaction brings out mechanical energy
What is the difference between electrical polarisation and dielectric polarisation?
in electric polarization ion is formed which have more tendency to form then magnetic polarization . in magnetic polarization just transfer of electron via flux . so the basic reason is that ion has more mobility constant then electron.so electric polarization is more faster then magnetic polarization.
What is the dual nature of electromagnetic waves and how they travel in a vacuum and through a medium?
electromagnetic waves can be regarded either as particles (photons) or as waves. An electromagnetic wave is composed of an electric field wave and a magnetic field wave. As the electric field collapses it induces a magnetic field which induces an electric field that opposes the first one. That electric field induces a magnetic field and so forth. Each field induces the next. It's rather more complex than that but you'd have to get into Maxwell's equations and Pointing vectors to get closer to the truth.
Electromagnetic waves are more commonly known as?
Waves of energy, particuraly atoms that have absorbed enrgy and altered their charge. These particles are called 'Photons', which transports various forms of energy throughout the world, such as light, microwaves, radiowaves, etc. ... ... ... The waves are of the strengths of electric and magnetic fields. A changing magnetic field induces an electric field, and a changing electric field induces a magnetic field, so the wave is self-sustaining unless interrupted or absorbed.
Could an electromagnetic wave travel through space if its electric and magnetic fileds were not changing with time?
i think the answer is yes, we get electromagnetic waves from the sun so...........
How does a guitar make a noise?
Acoustic: The string vibrates - this causes the sounding board of the guitar to vibrate at the same frequency (note). The velocity of a wave through the soundboard is higher than that of the string, so the soundboard causes sounds much louder than the strings. Electric: The string vibrates, which disrupts the magnetic field of the pickups. Whatever frequency a string vibrates at causes a different magnetic flux. An electrical current can be induced by a change in magnetic flux. This current is sent to an amp, which produces the sound.
Where is the magnetic rock located called magnesium?
mostly where i live; in texas ; because texas is so high in drout it makes the earth's magnetic feild harden :)
Why steel becomes a permanent magnet after electric current is passed through it?
Electric current is magnetic so when electric current pass through steel , steel will have the electric power and may be magnetic for awhile
Do circuits or electric currents have a magnetic field?
I think so
How is an electromagnet wave generated?
We produce electric field and magnetic field. If we change the electric field with time (so magnetic field alse change), required frequency, then we produce electromagnetic wave.
Why photon show both electric and magnatic field?
Protons are positively charged that's why they show electric field while magnetic field develops when electric field is in either direction so protons develops magnetic fields also.
A moving magnet produces an electric current is this true?
A changing magnetic field produces an electric current, so yes. This is true.
Are electric currents magnetic?
A magnetic field is always associated with a moving charge. So, if current is there, it must be showing the magnetic effects though these are too small of daily relevance..
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.
Why Do transverse magnetic mode has no magnetic line is in direction of propagation?
No. It has. Since transverse electric mode has it's wave propagating in the Z direction, and has magnetic field existing in the same direction with NO electric field... Likewise, transverse magnetic mode has it's wave propagating in the Z direction and has electric field existing in the same direction with NO magnetic field.
What is magnetic relunctance?
Reluctance is the opposition offered by a magnetic circuit to the formation of magnetic flux. It is equivalent to resistance in an electric circuit.Reluctance is the ratio of a magnetic circuit's magnetomotive force (measured in amperes) to its magnetic flux(measured in webers, pronounced 'vay-bers'). So, reluctance is measured in amperes per weber (which is often 'spoken' as 'ampere-turns per weber'). This is equivalent, in an electric circuit, to the ratio: electomotive force to electric current.
Does everything have a magnetic field?
No. Magnetic field arises due to a specific arrangement of electrons inside a substance. Hmm, I'd guess Yes. When there is electricity, there is a magnetic filed. Whenever an electron moves, not only does its electric field move, but also a magnetic field may be appreciated (if you are not moving with the electric field). OK, so gravity doesn't have a magnetic field.
