... Answer: C and D attract, B and D attract. Solution: From the first and third pairs of plates we see that B and D must have opposite charges, so they attract. The charge in a neutral copper plate will be polarized in such a way that if D is, say, positively charged, negative charge will be drawn to t ...

The Stern Gerlach Experiment Abstract
... We have known since the discovery of the Zeeman effect that atoms have magnetic dipole moments. Bohr’s theory supposed the quantization of angular momentum, and therefore the magnetic moment, but assumed only circular orbits. Sommerfeld later furthered this theory to include elliptical orbits, and i ...

Magnetic monopole
A magnetic monopole is a hypothetical elementary particle in particle physics that is an isolated magnet with only one magnetic pole (a north pole without a south pole or vice versa). In more technical terms, a magnetic monopole would have a net ""magnetic charge"". Modern interest in the concept stems from particle theories, notably the grand unified and superstring theories, which predict their existence.Magnetism in bar magnets and electromagnets does not arise from magnetic monopoles. There is no conclusive experimental evidence that magnetic monopoles exist at all in our universe.Some condensed matter systems contain effective (non-isolated) magnetic monopole quasi-particles, or contain phenomena that are mathematically analogous to magnetic monopoles.
