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...
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. ...
Magnetism - Magnetic Fields, Forces, Materials: All matter exhibits magnetic properties when placed in an external magnetic field. Even substances like copper and aluminum that are not normally thought of as having magnetic properties are affected by the
From this point of view, the magnetic force F on the second particle is proportional to its charge q2, the magnitude of its velocity v2, the magnitude of the magnetic field B1 produced by the first moving charge, and the sine of the angle theta, θ, between the path of the second part...

'Opposites attract'. You must have heard this phrase quite often. But why do opposites attract? Where did this phrase originate from? This phrase comes from the magnet and its magnetic field. The opposite poles of a magnet attract each other. Let us stud
He has taught high school chemistry and physics for 14 years. View bio Learn the magnetic force formula, learn how to determine the magnetic force direction, understand the magnetic field equations, and discover the relationship between a magnetic field and an electric current. Updated: 11/...

There is another quite different field that exerts forces on electric charges only if they are moving. Equally strange, the strength of the exerted force depends upon the direction of the charge's motion. This peculiar behavior reveals the presence of a magnetic field .These keywords were added...
