The PH0803 Magnetic Field Demonstrator shows the configurations of magnetic fields in one or two dimensions.
Plates with matrices of 98 small circular chambers contain an iron rod, which functions as effectively as a plotting compass. The transparent plates can be arranged in various ways including as faces of a cube or as a single large two-dimensional surface. This versatility allows you to show the configuration of magnetic fields in one or two dimensions. The transparency of plates also allows for overhead demonstrations. Size: 153 x 76 x 6mm. Does not include magnet.
