Magnetic properties of Matter

Eh-1 Curie Point of Gadolinium

Published: Tuesday 14 March 2006

To demonstrate the disappearance of ferromagnetism in Gadolinium above a certain temperature called the Curie Point.

Eh-2 Hysteresis

Published: Tuesday 14 March 2006

To demonstrate the B-H hysteresis curve.

Eh-3 The Hall Effect in P and N Type Germanium

Published: Tuesday 14 March 2006
