As is well known, when electric current flows in a straight wire, a charge in motion in the vicinity of the wire, parallel to it, is affected by a force called the magnetic force, which is attributable to the relativistic contraction effects that the wire undergoes in the frame of referenc...
Magnetism - Electric Currents, Forces, Fields: Magnetic fields produced by electric currents can be calculated for any shape of circuit using the law of Biot and Savart, named for the early 19th-century French physicists Jean-Baptiste Biot and Félix Sav
Magnetism, phenomenon associated with magnetic fields, which arise from the motion of electric charges. It can be an electric current in a conductor or charged particles moving through space, or it can be the motion of an electron in an atomic orbital. L
An example of electricity is the flow of electrons, i.e., current, in an wire. A flow of electrons in a wire also creates a magnetic field around the wire. What is difference between electricity and magnetism? Electric fields and forces are created by electric charges, whether the charge...
electromagnetism- magnetism produced by an electric current; "electromagnetism was discovered when it was observed that a copper wire carrying an electric current can magnetize pieces of iron or steel near it" antiferromagnetism- magnetic field creates parallel but opposing spins; varies with temperature...

current. Experiments with the coil demonstrate also the linearity of the output with the magnetic moment over the relevant range of magnetic moments independently of an external magnetic field H up to at least 20 kOe. Magnetization as a function of the electric field. Having calibrated the system...
A circulating magnetic field is produced by an electric current and by an electric field that changes with time. [7] Mathematically, it is given by: Where µ and ε are constants of media and J is current density measured in A/m2. It is given from Ohm’s law of electrostat...
