This current weight can be used for demonstration and measurement of an electric current's influence on a magnetic field (Laplaces law).
The product consists of a set with interchangeable magnets, as well as a tiltable holder on which a 4 mm plug pin can be used to mount small print circuits with a current conductor that varies in length from 8-6-4-3-2-1 cm. To create variation in the magnetic force created in the magnetic field, the current in the conductors may vary in the range 0 - 5 A DC. To measure the variation from the magnetic force, a weight that can be measured with a resolution of 0.01 g is required. The magnet holder with magnets has a weight of 167 g, and it is recommended that the assembly use a weight such as e.g. 102964 (not included).
