... Answer on Question #66811, Physics / Electromagnetism An electron moving parallel to the x-axis has an initial speed of 3.70×(10)^6 m/s at the origin. It's speed is reduced to 1.40×(10)^5 m/s at the point x=2c.m -calculate the electric potenial difference between the origin and that point? Find: vE ...

... earth=s magnetic field. Most earth scientists think that moving charges looping around within the earth create its magnetic field. Because of the earth‟s great size, the speed of moving charges would have to be less than one millimeter per second to account for the field. Another candidate for the e ...

... Magnetic North: Think of the earth as a giant magnet (it is actually). The shape of the earth's magnetic field is roughly the same shape as the field of a bar magnet. However, the earth's magnetic field is inclined at about 11º from the axis of rotation of the earth, so this means that the earth's m ...

Magnetochemistry
Magnetochemistry is concerned with the magnetic properties of chemical compounds. Magnetic properties arise from the spin and orbital angular momentum of the electrons contained in a compound. Compounds are diamagnetic when they contain no unpaired electrons. Molecular compounds that contain one or more unpaired electrons are paramagnetic. The magnitude of the paramagnetism is expressed as an effective magnetic moment, μeff. For first-row transition metals the magnitude of μeff is, to a first approximation, a simple function of the number of unpaired electrons, the spin-only formula. In general, spin-orbit coupling causes μeff to deviate from the spin-only formula. For the heavier transition metals, lanthanides and actinides, spin-orbit coupling cannot be ignored. Exchange interaction can occur in clusters and infinite lattices, resulting in ferromagnetism, antiferromagnetism or ferrimagnetism depending on the relative orientations of the individual spins.
