Examples: electromagnetic devices (such as a solenoid, motor, bell, or relay), cathode ray tube, mass spectrometer, antenna Changing electric fields generate magnetic fields and changing magnetic fields generate electric fields. Magnets contain two poles: “north” and “south”. Like poles (from different magnets) repel, unlike poles attract. A moving charge produces both an electric & magnetic Whereas the Lorentz force law characterizes the observable effects of electric and magnetic fields on charges, Maxwell’s equations characterize the origins of those Key Differences Between Electric Field and Magnetic Field. Conversely, a changing electric field can also induce a magnetic field, as described by Ampère’s law Describe qualitatively various technologies that use electric and magnetic fields. It can be generated by moving electric charges. Outside a magnet, field lines Magnetic field) A moving charge or current creates a magnetic field in the surrounding space (in addition to E)) The magnetic field exerts a force F m on any other moving Magnetic Field: A magnetic field is a field explaining the magnetic influence on an object in space. The area around Difference between Electric Field and Magnetic Field. A magnetic field is an invisible force field generated by a moving electric charge (current), spinning electrons, and magnets Magnetic Field Electric field) A distribution of electric charge at rest creates an electric field E in the surrounding space) The electric field exerts a force F E = q E on any other charges in presence of that field. The only difference between these two exists in the elementary quantum of the field. Field lines can be traced out by a small compass The changing magnetic field creates a circulating electric field, which can lead to the flow of electric current in a conductor (such as a wire) if the circuit is closed. The electric field is a pole, the magnetic field is a dipole in nature, magnetic monopoles though acceptable by the theories, have not been found An important difference between the electric field and the magnetic field is that the electric field does work on a charged particle (it produces acceleration or eleration) while the magnetic field does not do any work on the moving charge Magnetic Field. This magnetic field can be visualized as a pattern of circular field lines surrounding a wire The electric field is actually the force per unit charge experienced by a non moving point charge at any given location within the field, whereas the magnetic field is detected by An important difference between the electric field and the magnetic field is that the electric field does work on a charged particle (it produces acceleration or eleration) while The Maxwell equations (Section) are direct relations between electric and magnetic fields. Outside a magnet, field lines start from the north pole, end at the south pole. This is reminiscent of the electric force between two charged objects (which can have positive or negative charge) The equations determine how fields arise from distributed charge and current and The electric field is the area surrounding a charged particle while the magnetic field is the area surrounding a magnet. The region around the electric charge where the electric force exists is called an electric field. Like field lines in an electric field, magnetic field lines are used to illustrate the field. Electric Field: A electric field is a field defined by the magnitude of the electric Electric Current and Magnetic Fields. Electric current produces a magnetic field. Magnetic field) A moving charge or current creates a magnetic field in the surrounding space (in addition to E) Like field lines in an electric field, magnetic field lines are used to illustrate the field. The direction of the magnetic field is indicated by lines The electric field is actually the force per unit charge experienced by a non moving point charge at any given location within the field, whereas the magnetic field is detected by the force it exerts on other magnetic particles and moving electric charges An electric field is an invisible force field caused by an electric charge resulting in an alteration of space (air or vacuum) around the charge. The magnetic field is the area around a magnetic body or a moving electric charge within which magnetic force acts. The force between like-poles repels (north-north, south-south), while opposite poles attract (north-south).
