What are the interactions between magnetic objects and electrical circuits?

Magnets actually generate electricity. When a wire is passed through a magnetic field it produces electron flow. Coils of wire can detect magnetic flux variation and be used as sensors.

How do convert kinetic energy into electrical energy?
This is done with a so-called "generator". It uses the interactions between electricity and magnetism to convert the movement to an electrical current. That is, if a conductor moves through a magnetic field, a voltage is induced.

Turn electrical energy into mechanical energy?
The main principle of an electric motor is converting the electrical energy in to mechanical energy.when electricity flows in a closed circiuit it exhibits electromagnetic waves around it...in similar this passion when coil of copper wire are placed in between magnetic poles,when electicity flows in the coil,the magnetic waves by the coil are reflected by the magnetic poles we placed so this in turn produces torque..That is mechanical work ..so in this way we can turn electrical energy into mechanical energy
What is the difference between an electrical wave and a magnetic wave?
In the general sense, a magnetic circuit is any path taken by magnetic flux. More specifically, it is associated with the magnetic flux within (usually) silicon steel 'cores' such as those found in transformer, generators, motors, relays, etc. They can be 'homogenous', where the flux path is completely contained with the same material (e.g. a transformer core), or 'compound', where the flux path incorporates, say, an air gap (e.g. motor/generator fields).A magnetic circuit can be compared with an electric circuit, where-magnetomotive force (mmf) is equivalent to electromotive force-flux is equivalent to electric current-reluctance is equivalent to resistanceThe source of a magnetic circuit's magnetomotive force is a current-carrying coil. The magnitude of this mmf is the product of the current flowing through the coil, and the number of turns (I x N). Since the number of turns is dimensionless, the SI unit of measurement of mmf is the ampere (A), although it is frequently 'spoken' of as 'ampere turns', to avoid confusion with the unit for electric current.Magnetic flux is measured in webers (Wb), pronounced 'vay-bers'.Reluctance is measured in amperes per weber (A/Wb) although, again, it is frequently spoken as 'ampere-turns per weber'.Another similarity with electric circuits, is that the equivalent of 'Ohm's Law' also applies to magnetic circuits: i.e. flux = mmf / reluctance.Finally, magnetic circuits can also be compared with series, parallel, or series-parallel circuits, but this is beyond the scope of this answer!
How are electrical circuits different from magnetic circuits?
What are the differences between electrical and magnetic circuit.
What is meant by mutualism?
conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.
What is meant by mutual coupling?
conection between two or more magnetic circuits magnetically with out any electrical connection .i.e.'flux linkages are there inbetween the magnetic circuits.
How power plants generate electrical energy from kinetic energy?
They use a generator, which in turn uses the interactions between electric and magnetic fields. Basically, if a wire moves through a magnetic field, a voltage will be induced.

What is one difference between electricity in lighting and the electricity in an electrical circuit?
Lightening is natural. Electrical circuits are man invented and made.

answer
What interactions between electrical and chemical gradients does not lead to the establishment of a neuron's resting potential?
Electrical forces push sodiun ions out of the cell
Why are there gaps between electrical lines?
Electrical flow creates magnetic fields around the wires. The distance helps prevent interruptions and problems in the flow.
Why do you have to study about electrical circuits in electrical engineering?
Electrical circuits are just one aspect of electrical engineering, and a huge aspect at that. The core groupings within electrical engineering are electricity, electronics, electromagnetics, and photonics (of course there is a lot of overlap between these, as well as more sub-groupings). Electrical circuits mostly fall under the electronics category. To put it in perspective, studying EE without studying electronic circuits would be like studying chemistry without studying chemical reactions. Study or understand? if you do not understand it is best to study it. I am always studying new electrical circuit technology just to keep up with our changing world. Some say why and others say why not.
