... No, this does not violate conservation of energy. In moving the magnet closer the armature, you have changed the motor design to make it more efficient. Efficiency equals the power out divided by the power in. Since the armature spins faster when the magnet is closer, the power out is greater. Since ...

... Have a second participant come to the front and empty the contents of Bag B onto the table. Ask them to predict, based on the findings of the previous test, which objects will be attracted to the magnet. Upon actual testing, they will discover that only some of the metals in Bag B are attracted. 3. ...

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.
