bar magnet वाक्य

Atoms do not actually spin but the property is a quantum-mechanical effect analogous to a tiny bar magnet that can be twisted by the light.
Is it just like a permanent iron bar magnet with magnetic domains locked in alignment ?-- talk ) 19 : 30, 9 November 2009 ( UTC)
The field is similar to that of a bar magnet, running vertically down the center of the inner cylinder and up the outside of the apparatus.
But besides their electric charge, electrons also have a less exploited property : " spin, " an angular momentum that makes electrons act like tiny bar magnets.
If a bar magnet were used to wrap the wire around, then the effect of the electromagnetism might add to or subtract from the magnetism originally present.

These pickups have a large, flat coil with adjustable steel screws as pole pieces, and a pair of flat alnico bar magnets lying under the coil bobbin.
If the earth were a perfect bar magnet, sending out its fields in long arcs, then the field lines at the magnetic equator should parallel the earth's surface.
For example, the direction of the magnetic moment of a bar magnet, such as the one in a compass is the direction that the north poles points toward.
Sidles'scheme starts with the basic principle of MRI, which exploits the magnetic moment of protons and neutrons _ that is, their tendency to act like tiny bar magnets.
A bar magnet would typically be steel or a " hard " ferrous substance which retains a portion of the applied magnetic field when the current is turned off.
