It was first reported in 1823 that when a temperature gradient is applied to a sample of an inhomogeneous material an electromagnetic disturbance can be detected near the surfaces of the material – see:

The instruments used for measuring electromagnetic effects today are much, much, much, much, much, much more sensitive than anything available back then. You’d think that members of the dental profession would have been keen to use these instruments to
demonstrate that no electromagnetic disturbance can be detected near the surfaces of samples of dental amalgams when temperature gradients are applied to them.

(Perhaps they tried, found out that this could not be done, and decided not to tell anyone.)

Does anyone know of any reason why the materials used in restorative dentistry should be exempt from the laws of nature?
