Magnetic Anomalies and Calculating Spreading Rates
... 1. On each track on the back, mark points where the magnetic curve intersects the line of zero field strength. Start at the ridge and work outwards on both sides. These points are the points of reversals, when the magnetic pole switches from normal to reversed polarity or vice versa. Use a pencil! 2 ...

2015 Q10 - Loreto Balbriggan
... An electron can be detected in a cloud chamber. However it is much more difficult to detect a neutrino. Explain why. In a cloud chamber an electron travels perpendicular to the direction of a magnetic field of flux density 90 mT and it follows a circular path. Calculate the radius of the circle when ...

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.
