La suscettività magnetica al variare della temperatura

We present an experiment to measure the temperature dependence of magnetic susceptibility of a dia-magnetic material such as pyrolityc graphite. Pyrolityc graphite is a typical diamagnetic material and can levitate in a strong magnetic field. the levitation height was changed by varying the pyrolityc graphite temperature using a lighter. the magnetic flux was calculated using a simulation software and the mag-netic susceptibility temperature dependence was discussed. the activity was experimented in an italian high school.
