Description

All materials are at least slightly diamagnetic, meaning that the material’s internal magnetic field opposes external fields and therefore slightly repels. Aluminum, however, is a paramagnetic material, meaning that it’s internal magnetic field adds to an external field. Alternating current is used to produce a magnetic field in a large coil. The current in a second coil is monitored to measure how well this magnetic field travels through aluminum sheets. A decrease in the magnetic field shows that even though aluminum is a paramagnetic material, it can exhibit diamagnetic properties as a result of induction. The effect of thickness and size of the aluminum sheets on the resulting magnetic field is observed.
