What causes electric fields and how are they related to magnetic fields?

Classically, electric fields are created by one of the following two ways:\n\n1.  Charged particles (e.g. electrons, protons)\n(keep in mind, these charged particles could be moving or stationary... doesn't matter... and electron in space whether it's moving or not has an electric field associated with it...)\n2.  A time-varying magnetic field\n\nMagnetic fields are created by one of the following two ways:\n\n1.  Moving charged particles (current) \n2.  A time-varying electric field\n\nAn electromagnetic wave in free space can be though of as the following:\n\nA time varying electric field creates a time varying magnetic fields which in turn creates a time varying electric field which in turn creates a time varying magnetic field... etc. etc. and this process propagates just like a wave on water except it doesn't need any medium (like water or some sort of ether) to propagate.

Where ever an electic charge is made to oscillate there will be electic field and magnetic field.\n\nNowadays every one is familiar with cell phones.The cell phones receive the electric and magnetic field produced at the transmitting end.\n\nRadio ,T.V are other examples of receiving electic and magnetic fields.Very very familiar example is the light which we see.\n\n Light is one form of electic and magnetic field. Hence whenever we open our eyes we feel the precence of electic and magnetic field.\n\nAs a crude answer  when ever we see we find electric and magnetic field.

Because the flowing of electrical current causes a magnetic field to be created which interacts with the outer core windings of the generator.  The turning of the inner core creates an opposing magnetic field in the outer (eletric core) and they interact.

Static electricity is caused by electrons being removed from a body, such as you. when this body is not an electrical conductor, it becomes ion charged.Once that body is ionically charged other bodies which are opposingly charged are attracted.

According to Maxwell's laws, one type of field can induce the other and vice versa. This makes electromagnetic waves possible.

In physics, a magnetic field is an entity produced by moving electric charges (electric currents) that exerts a force on other moving charges. (The quantum-mechanical spin of a particle produces magnetic fields and is acted on by them as though it were a current; this accounts for the fields produced by "permanent" ferromagnets.) A magnetic field is a vector field: it associates with every point in space a (pseudo-)vector that may vary in time. The direction of the field is the equilibrium direction of a compass needle placed in the field.

I hope you are familiar with atomic theory if not get familiar and come back to this. as an electron moves it creates a wake much like a boat moving through water this wake is called a magnetic line of force. if a nother electron is encountered by this wake it will be influenced by it like a surfer on a wave. an electromagnetic fiel is the area of influence of these waves. in most materials the electrons are moving in many different directions, hence the sum field is random and weak. however if most of the electrons are coerced into a uniform movement the individual lines become coherent and combine to provide a polarised field with a stronger magnetic influence moving this fiel across an object will cause the electrons in it to surf and produce an electric current. however these surfing electrons will produce a magnetic field that is the opposite of the field they are surfing on.

Electrostatics is the study of static or non time varying electric fields.\n\nElectromagnetics is the more general term applied to the study of electric and magnetic force fields.  Usually most situations deal with time varying currents producing time varying magnetic fields.  Maxwell's equations show us that time varying magnetic fields produce time varying electric fields.\n\nThe rest of electromagnetics is the study of the physical properties of these force fields, how they behave in a conductor, how antennas can radiate these fields, etc.

(m)\n\nThe electric and magnetic field associated with most electrical appliances and power lines are at the extremely low frequency end of the electric and magnetic spectrum. They have a frequency of 60 cycles per second, or 60 hertz (60 Hz), because the alternating electrical current that creates them changes direction 60 times per second. Radio and television broadcast waves are farther up the electric and magnetic spectrum. Visible light, which is at an even higher frequency yet, is the most familiar form of electric and magnetic energy.

Electricity is a property of matter that results from the presence or movement of electric charge. Together with magnetism, it constitutes the fundamental interaction known as electromagnetism. Electricity is responsible for many well-known physical phenomena such as lightning, electric fields and electric currents, and is put to use in industrial applications such as electronics and electric power.

The difference lies in the nature of the fields. The electric fields can affect every charged particle whether it is static or moving but magnetic field can affect it only if its moving that even not along the magnetic field lines. The force due to electric field follows F=qE and is in the direction of the field itself whereas the magnetic force follows F=q(vxB) and is in the perpendicular direction to the magnetic field and thus causes the charge particle to gyrate around the field lines. Moreover the work done by a magnetic force is zero unlike in the case of an electric force.

Accelating charges (and only accelerating) always produce magnetic fields in the space around them. So with AC current the charge carriers are contually changing direction and must hence be accelerating and so produce magnetic fields. The flux rises and falls before reversing direction with each change in current direction

I have nver heard of an electric current being effected by light, so my first inclination is to say no.\n\nHowever, if you think of light as an electromagnetic wave, a set of orthagonal electric and magnetic fields, it may be possible.\nAn electric current is simply the flow of charged particles (usually electrons).\nWe know that an electric field will effect an electric current (opposite charges attract, like charges repel).  We also know that a magnetic field will effect a current (moving electric current generated magnetic field and exerts a force on an electricly charged particles).\nSo it may be possible for the moving electric and magnetic fields to interfere with the electric current, but I am not entirely sure.

As we know that current also has a electric and magnetic field i.e is also electromagnetic in nature.\nWhat happens is that the electric and magnetic fields of current in a path offering resistance radiate these fields strong enough for them to propogate.\n\nkaran

Static electricity is caused by friction. When the air is dry like in winter there is more friction.
