Around an alternating current or a fluctuating direct current, the magnetic field is continuously changing its magnitude and direction. magnets and their associated magnetic field linesA permanent magnet (such as a bar or disk magnet) possesses a magnetic field by virtue of the alignment of all ...
around the wire is the direction of the magnetic field around the wire. For example, if the current were coming straight out of this page toward you, your thumb would be pointing toward you and your fingers would indicate a counter-clockwise direction to the magnetic field around the wire. ...

Magnetic Field is the region around a magnetic material or a movi...
When an electric current traverses a straight wire, it induces a magnetic field whose lines of force are concentric circles centered around the wire. This configuration illustrates the intimate relationship between electricity and magnetism, highlighting how electrical currents can create magnetic environmen...
A magnetic field is avector, which means it has magnitude and direction. Ifelectric currentflows 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 th...
Magnetic field, a vector field in the neighborhood 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 lin
XV. A note on the magnetic field of a rectilinear circuit and the attraction of a straight wireThis paper presents a summary of all catch-comparison gear tests performed between 2002 and 2006 with Nordmre-type sorting grids in the Swedish Nephrops trawl fishery in the Skagerrak and Kattegat....
have inductive fields which the working physicist and electrical engineer need to keep track of in order to get a mathematical hold on either field's electrical and physical effects. But it is not helpful to drag around confusing names. A straight wire current's inductive field is just that....
