Apparatus
for Laplace’s
law
This apparatus is the force on a conductor in a magnetic
field. It consists of a pair of aluminium rails with 4 mm

terminals. An aluminium axle with plastic discs can roll
freely along the rails and thus completes the electrical
contact be tween them. A strong U-shaped magnet is
required to complete the app., use e.g. our no. 3315.00
