text: Magnetic fields are produced by moving electric charges and the intrinsic magnetic moments of elementary particles associated with a fundamental quantum property, their spin.
text: An electric field is produced when the charge is stationary with respect to an observer measuring the properties of the charge, and a magnetic field as well as an electric field is produced when the charge moves, creating an electric current with respect to this observer.
text: He discovered that magnetic fields are produced by moving charges ( current ).
text: A magnetic field is produced by moving electric charges and intrinsic magnetic moments of elementary particles associated with a fundamental quantum property known as the spin.
text: Magnetic Field created by a Current-Carrying Conductor Ampere suggested that a magnetic field is produced whenever an electrical charge is in motion.
text: Electric fields are created by charges at rest relative to an observer, whereas magnetic fields are produced by moving charges.
text: If the charge is moving, a magnetic field is also produced.
text: To understand what's happening, says Glatzmaier, we have to take a trip ... to the center of the Earth where the magnetic field is produced.
text: To understand what's happening, says Glatzmaier, we have to take a trip ... to the center of the Earth where the magnetic field is produced.
text: Astronomers believe that the magnetic field is produced closer to the surface of the planet.
text: Much stronger magnetic fields can be produced if a "magnetic core" of a soft ferromagnetic (or ferrimagnetic) material, such as iron, is placed inside the coil.
text: Recall from the beginning of the Electromagnetic Radiation chapter, that a magnetic field can be produced by circulating electrical charges.
text: But when electric field is moving at a uniform speed then a magnetic field will be produced.
text: A magnetic field can be produced when an electric current is passed through an electric circuit wound in a helix or solenoid.
text: When current flows through the coil, a magnetic field is produced.
