How is an electronic magnetic field created?

If electricity is the flow of negatively-charged particles called electrons, what positive-charged particles are present near these electrons to create a magnetic field?

    Your choice of words is poor. 

    How is an electromagnetic field created? 

    By using electricity and electrical conductors. 

    A ferrous core would help.

    No positive charges are needed. The electrons make the magnetic field. Any moving charge creates a magnetic field. Its strength and direction is given by Maxwell's equations.

    First you plough and then sow electro magnetic seeds .

    first learn how electricity is made negative charged whata laugh , electric fields have to occur after all electricity is made from magnets , also look at sine waves , ac electricity has a sine wave , dc doesnt.

    Magnetism appears at right angles to MOVING electrons.-----If the electrons are moving in a wire flowing from negative to positive---OR doing their thing circling the nuclei of atoms.   Magnetism and electrons are directly related   Moving one creates the other.

    So if we move electrons in a current through a coil of wire, Magnetism emitted from each loop of wire will reinforce the loop next to it and make the field stronger and bigger.---Putting a metal core within the field of the coil will concentrate it and make it stronger still----We call it an ELECTROMAGNET.

    "Electricity" doesn't really have a formal definition in physics/electronics and you will never see it used in that context other than as a catch-all term for the phenomena associated with charged particles. In casual usage by lay people electricity is variously used to mean any of the following; electrical energy, power, charge, current, voltage and electric field - which are all different things.

    an Electro-Magnetic field is created any time a current flows in a conductor.

    Simple answer: protons. Every atom has one or more protons.

    Slightly less simple: you don't need positive-charge particles to create a magnetic field.  A beam of electrons will create a magnetic field all by itself.

    why do you think positive-charged particles are needed to create a magnetic field  ?  no, just a flow of current is all that is needed, which is usually a flow of electrons. 

    And, your definition of electricity is wrong. A current can be a flow of electrons, or a flow of positive ions. Static electricity is just an excess or deficit of electrons or other charged particles. 


    Electricity is the set of physical phenomena associated with the presence and motion of matter that has a property of electric charge. Electricity is related to magnetism, both being part of the phenomenon of electromagnetism, as described by Maxwell's equations. Various common phenomena are related to electricity, including lightning, static electricity, electric heating, electric discharges and many others.
