... Can anyone think of a way we could rearrange this human/chicken circuit so that if we broke the connection at the first chicken, the second would keep on chirping? (Move some of the students, including the second chicken, into or outside of the circle. Close the original circle and check that the fi ...

Magnetic Mysteries
... This is a demonstration of two things: electromagnetic induction and Lenz's Law. Copper is not magnetically sensitive, but it is an excellent conductor of electricity. When either magnet falls through the copper pipe, there is a current of electricity that is induced. The neodymium magnet creates a ...

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.
