magnetic field n. A condition found in the region around a magnet or an electric current, characterized by the existence of a detectable magnetic force at every point in the region and by the existence of magnetic poles. American Heritage® Dictionary of the English Language, Fifth Edition. ...
antiferromagnetism- magnetic field creates parallel but opposing spins; varies with temperature diamagnetism- phenomenon exhibited by materials like copper or bismuth that become magnetized in a magnetic field with a polarity opposite to the magnetic force; unlike iron they are slightly repelled by a ma...
The magnetic force on a moving charge is exerted in a direction at a right angle to the plane formed by the direction of its velocity and the direction of the surrounding magnetic field.The Editors of Encyclopaedia Britannica This article was most recently revised and updated by Adam Augustyn....
Force on a Wire in a Magnetic Field, Nature 246, 208 - Lowes - 1973 () Citation Context ... can be calculated via the interaction of the current and magnetization in the wire with only the fields present before the wire was added to the problem, as emphasized in sec. 35 of [18] ...
Derivation Field Force Magnetic Magnetic field Magnetic field and forces Magnetic moment Moment Torque In summary, I am trying to derive the equation Γ→=m→×B→, where m→=IA→ is the magnetic moment, and A→ is normal to surface A, from the Lorentz force law dF→=Idl→×B→. For...
