A printed circuit board coil on support handle with 5 and 10 turns rated at 2A.
A printed circuit board coil on support handle with 5 and 10 turns rated at 2A. The lower arm of the coil is 75mm long (minimum) and 20mm wide.
In use the coil is supported between the poles of 2 ferrite slab magnets on a yoke or in the adjustable magnet on the top pan of an electronic balance. When a current is passed through the coil the force can be easily measured by the change in reading on the balance and investigations into F=BIL can be carried out.
