Can a body or object do work?
Yes it can! In physics work is the number of joules per second that the object or body (assuming large planetary body) uses or emmits per second, work is measured in Watts and it is usually electromagnetic radiation that carries this energy.
What Several ways we use electromagnetic induction in our daily lives?
Electromagnetic induction is the production of voltage across a conductor moving through a magnetic field. It underlies the operation ofgenerators, all electric motors, transformers, induction motors, synchronous motors, solenoids, and most other electrical machines.Also the metal detectors work on the principle of electromagnetic induction.
What is relation between electric field and energy?
Electrical energy is produced through the motion of a conductor within an electromagnetic field produced by a magnet. In this way, electromagnetic fields are absolutely critical to the production of electric energy.
How do Transrapid Maglevs Slow and Stop?
Transrapid Maglevs slow down and stop using a combination of electromagnetic brakes and eddy-current brakes. Electromagnetic brakes work by applying a magnetic field to the track, which induces a current in the moving magnets of the train, creating a force that opposes the motion. Eddy-current brakes work by creating a magnetic field that interacts with the conducting track, generating eddy currents which create an opposite magnetic field that slows down the train. These braking systems work together to gradually slow down and bring the Transrapid Maglev to a stop.
Can electric field lines do work?
Yes. Work is force times distance, or technically the dot product of vector force times vector distance. Electric fields exert force on charge and the force does work when the charge moves in the direction of the electric force. (In the converse, when the movement of charge is against the direction of force, work is transformed into stored electromagnetic energy.) Technically, it is the electric field that does work and not the field line. Mother nature produces electric fields, but humans can not see electric fields. Humans invented the idea of field lines to create a mental picture of the field. The two most common ways are to draw lines in space or to draw a collection of arrows in space. Note: One should not confuse this answer with the question of whether work can be done by a magnetic field. A magnetic field can not do work because the direction of the magnetic force is always perpendicular to the direction of motion of charge and hence the dot product of force and distance moved is always zero.
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.
How does the process of electromagnetic induction work?
The process by which a substance, such as iron or steel, becomes magnetized by a magnetic field. The induced magnetism is produced by the force of the field radiating from the poles of a magnet.
What electromagnetic wave does a camera use?
it uses a radio wave as it has a big wave length. it is an electro magnet that needs to be heated to work.
How does electromagnetic bell work?
A electromagnetic bell works by a electrical circuit.
What is a photon How does it work What is a photon's part in magnetism?
What: a photon is the boson that carries the electromagnetic force.How: I'm not sure there is an answer to this, the particle is a boson and carries a specific quanta of energy.What part: it carries the electromagnetic force in both electric and magnetic interactions between the objects involved.
What term is define as the words an author uses in literary work which is part of a literary style?
Diction is defined as the words an author uses in a literary work as part of a literary style.
How does the electromagnetic field work?
A electromagnetic field works by an electrical current flowing through an inductor which induces a magnetic field, as soon as the electrical current is switched off to the inductor, the electromagnetic field collapses.
What type of work uses heat technology?
Heating,ventilation,air conditioning,and refrigeration. only field I can think of... or by work do you mean work = power a.k.a. Btu/hour
How does the seismogragh work?
A seismograph uses electromagnetic sensors to measure seismic waves in order to detect earthquakes that are too small to feel, as well as detecting and tracking other phenomena.
Can a body or object do work?
Yes it can! In physics work is the number of joules per second that the object or body (assuming large planetary body) uses or emmits per second, work is measured in Watts and it is usually electromagnetic radiation that carries this energy.
How does a bulk tape eraser work?
A bulk tape eraser is an electromagnetic device that manipulates the magnetic field around it in a particular manner. When a tape (cassette, reel to reel, or VHS) is subjected to the magnetic field, the information is lost because it is demagnetized.
What type of search engine uses keywords to perform searches?
the keywords means define the category ,field.& work environment
