What is the magnetic effect of current?

Answer 1

'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.

Answer 2

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 :)

Answer 3

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.

Answer 4

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

Answer 5

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.

Answer 6

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.

Answer 8

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.

Answer 9

A real "electric motor" doesn't - but those things called electric motors are really magnetic motors.

Answer 10

its similar to the electro magnetism.
