'This seems like a question from an electrical course, and is probably best answered by your course materials.
It's your test question, not ours, and there won't always be someone to ask the answer of. Earn your diploma.'
-Just want to edit that last disgraceful response and say although I don't know the answer, I too was looking for information on this subject, out of pure interest. My mac's power input has a very convenient magnet on it, which keeps the plug from falling out of the laptop, I was wondering if the magnet would in any way change the movement of electricity going into my laptop. Whoever gave that last answer, you must be very stuck up.
The magnetic fiel of the magnet interacts with that of the current carrying wire placed between the two poles of the magnet. This means that the wire is either repelled or attrcated by one of the poles. however, this would mean that the wire moved into one position and stayed there. However, there is a split-ring commutator which changes the direction of the current in the wir every half turn, meaning that the magnetic fiel of the wire changes every half turn.
Hope this explained everything :)
Electromagnetic induction is how energy is transferred through a transformer. Transformers carry the magnetic force because they are magnetically permeable and affected by the magnetic energy.
The result is that the rotating parts of the motor start to spin.The electrical energy has been transformed into mechanical energy.Motors can move all sorts of things-from toy cars to huge locomotives
permanent magnets have magnetic force,directed from its north pole to its south pole.In D.C motors when a mold of current carrying wires interrupts this magnetic force, a mechanical push is generated, which runs a D.C motor.
Electric current is a flow of electric charge through a medium. This charge is typically carried by moving electronsin a conductor such as wire. It can also be carried by ions in an electrolyte, or by both ions and electrons in aplasma.
The SI unit for measuring the rate of flow of electric charge is the ampere, which is charge flowing through some surface at the rate of one coulomb per second. Electric current is measured using an ammeter.
Electromagnetism is one of the four fundamental interactions in nature. The other three are the strong interaction, the weak interaction and gravitation. Electromagnetism is the force that causes the interaction between electrically charged particles; the areas in which this happens are called electromagnetic fields.
Electromagnetism is responsible for practically all the phenomena encountered in daily life, with the exception of gravity. Ordinary matter takes its form as a result of intermolecular forces between individual molecules in matter. Electromagnetism is also the force which holds electrons and protons together inside atoms, which are the building blocks of molecules. This governs the processes involved in chemistry, which arise from interactions between theelectrons inside and between atoms.
Electromagnetism manifests as both electric fields and magnetic fields. Both fields are simply different aspects of electromagnetism, and hence are intrinsically related. Thus, a changing electric field generates a magnetic field; conversely a changing magnetic field generates an electric field. This effect is called electromagnetic induction, and is the basis of operation for electrical generators, induction motors, and transformers. Mathematically speaking, magnetic fields and electric fields are convertible with relative motion as a four vector.
Electric fields are the cause of several common phenomena, such as electric potential (such as the voltage of a battery) and electric current (such as the flow of electricity through a flashlight). Magnetic fields are the cause of the force associated with magnets.
In quantum electrodynamics, electromagnetic interactions between charged particles can be calculated using the method of Feynman diagrams, in which we picture messenger particles called virtual photons being exchanged between charged particles. This method can be derived from the field picture throughperturbation theory.
The theoretical implications of electromagnetism led to the development of special relativity by Albert Einstein in 1905.

Yes they are ! Magnets form an essential part of the electric motor. It's the interaction of the magnetic field with the electric currents in the coils of the motor that cause it to spin.
A real "electric motor" doesn't - but those things called electric motors are really magnetic motors.
its similar to the electro magnetism.
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy. In a galvanometer, the concept of the motor effect is used for it to detect and measure the magnitude of small electric currents as an instrument. A galvanometer uses radial magnets which cover more area of the rotor (this is where the needle is attached), as this rotor consists of an armature and loops of wire, it is perpendicular to the magnetic flux lines of the radial magnet. Therefore as the current flows through the coil, a magnetic field is produced, and the motor effect occurs allowing the needle to move on the scale.
There is no magnetic current because there are no magnetic charges.
An electric current produces a combination of three effects. These are the heating effect, the chemical effect, and the magnetic effect.The unit of measurement of current, the ampere(A), cold be defined in terms of any of these three effects. However, in SI, the ampere is defined in terms of its magnetic effect -i.e. the force of attraction or repulsion created by the magnetic fields surrounding two, parallel, current-carrying conductors. Prior to its present definition, current was defined in terms of its chemical effect -i.e. the amount of silver deposited by electrolysis over a given period of time.
Yes, a current carrying conductor behaves like a magnet.
A magnetic pole is where the magnetic effect is greatest.
The magnetic effect of electric current is known as electromagnetic effect. It is observed that when a compass is brought near a current carrying conductor the needle of compass gets deflected because of flow of electricity. This shows that electric current produces a magnetic effect.
The magnetic force acts only on moving electric charges; A constant electric current produces an unchanging magnetic field and a changing electric current produces a changing magnetic field.
If you are asking, 'What are the properties of an electric current?', then there arethree. They are (1) the magnetic effect, (2) the heating effect, and (3) thechemical effect. The unit of measurement of current, the ampere, is defined interms of the current's magnetic effect.If that's not your question, then this answer won't help you.WebRepcurrentVotenoRatingnoWeight
i dont care i LOVE it
it will produce a stronger magnetic field.
All electrical devices.
Hall Effect
flow of electrons is not visible.only it can be sensedAnswerCurrent can only be detected through one or more of its effects. There are three effects of an electric current: heating effect, magnetic effect, and chemical effect. We use the magnetic effect (the force between currents in parallel conductors due to their magnetic effects) to define the ampere.
a current flow close to a magnetic source it influence the sources hall effect is a disturbed signal as a function of speed.
Death, injury, and electricutionIf we ignore the above, humourous(!), attempt at an answer, then the three effects of an electric current are (1) heating effect, (2) chemical effect, and (3) magnetic effect.Examples of the heating effect include electric heaters, kettles, stoves, etc. An examples of the chemical effect is electroplating. Examples of the magnetic effect includes relays, motors, etc.The SI unit of current, the ampere, is defined in terms of the force between two parallel conductors due to their magnetic fields (i.e. the magnetic effect).
A motor effect is when magnetic flux lines interact with the current flow in the current conducting wire (a production of current means there is a production of a magnetic field, thus the magnetic field of a permanent magnet interacts with the magnetic field of the current), hence causing a motor effect, where electric energy is transformed into mechanical energy.

i don't believe it does
