We can observe that the magnetic field lines are in the form of concentric circles near the sides of the loop but towards the centre of the loop, the magnetic field lines become almost parallel which indicates that this part of the coil has a uniformmagnetic field. In other words, we can...

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
When any of the flux tubes that collectively make up a magnetic field continuum is dislocated and misaligned relative to the rest of the field, there is a ... EN Parker - 《Astrophysical Journal》 被引量: 135发表: 1981年 Rapid dissipation of magnetic fields due to Hall current We propose...
The magnetic field from a loop of current carrying wire in the plane of the page is directed out of the page. In which direction do the electrons in the wire loop move?( ) A.counterclockwise B.clockwise C.they all move to the right side of the loop D.they all move to the left ...
6. It corresponds to a distribution of displacement currents in {x,z} plane. Circular currents create magnetic fields according to the Biot-Savart law, which states that the magnetic field at center of a current loop is given by \(B=\mu I/2R\). For a current I = 1 A and ...
Real-time measurement of the magnetic field in an experimental region of space is not always practical or feasible. In most cases, the experimental region is not accessible due to a physical enclosure (e.g., a setup placed in a vacuum chamber), or it could be that placing a magnetic ...
Particularly, the solution of the electromagnetic field equation around a black hole immersed in an external asymptotically uniform magnetic field has been obtained in [37]. The modification of the astrophysical processes due to the electromagnetic field has been explored in Refs. [38,39,40,41,42...
