Definition of magnetic field the portion of space near a magnetic body or a currentcarrying body in which the magnetic forces due to the body or current can be detectedRead More
Magnetic field a vector field in the neighbourhood of a magnet electric current or changing electric field in which magnetic forces are observable Magnetic fields such as that of Earth cause magnetic compass needles and other permanent magnets to line up in the direction of the fieldRead More
A magnetic field is an area which is under the influence of a magnetic charge A magnetic field like an electric field is due to the polar nature of electric or magnetic charges Poles are oriented in north and south directions and a magnetic fields strength depends on the strength of the magnet that is creating it Magnetic fields are a basic principle behind countless appliances and modernday gadgetsRead More

A magnetic field is generated when electric charge carriers such as electrons move through space or within an electrical conductor The geometric shapes of the magnetic flux lines produced by moving charge carriers electric current are similar to the shapes of the flux lines in an electrostatic fieldBut there are differences in the ways electrostatic and magnetic fields interact with theRead More
The magnetic field is the area around a magnet in which there is magnetic forceMoving electric charges can make magnetic fields Magnetic fields can illustrated by magnetic flux linesAt all times the direction of the magnetic field is shown by the direction of the magnetic flux lines The strength of a magnet has to do with the spaces between the magnetic flux linesRead More
Dec 02 2019nbsp018332A magnetic field is a vector which means it has magnitude and directionIf electric current flows in a straight line the right hand rule shows the direction invisible magnetic field lines flow around a wire If you imagine gripping the wire with your right hand with your thumb pointing in the direction of the current the magnetic field travels in the direction of the fingers around the wireRead More
102 Magnetic field associated with a current ESBPS If you hold a compass near a wire through which current is flowing the needle on the compass will be deflected Since compasses work by pointing along magnetic field lines this means that there must be a magnetic field near the wire through which the current is flowingRead More
