Neutron demonstration

This item is designed to demonstrate the stabilizing effect of neutrons on the atomic nucleus. The "protons" are made of disc magnets while the "neutrons" are made of browned iron discs. The "protons" will, because they are magnetized, repel one another when placed on flat surface or overhead projector. The stabilizing effect of the "neutrons" is illustrated by placing them between the "protons", thereby eliminating the repulsive force. The "protons" are supplied with red marking, the "neutrons" with blue. Supplied as single pieces. The proton can be ordered under product code MO150900.
