Product Summary
The redesigned Variable Gap Magnet is rugged and durable, while providing excellent results as a demonstration tool. The two one inch (2.54 cm) diameter neodymium magnets are mounted on a heavy-duty cast iron base that has a threaded hole to mount on a support rod, which provides even more versatility. The gap may be varied from 0.5 cm to 8.9 cm using the adjustment screws. Two flat pole pieces are also included to provide a uniform magnetic field when needed.
Demonstrate Diamagnetism and Paramagnetism: A diamagnetic glass rod aligns transverse to the field while a paramagnetic aluminum rod aligns with the field.
The glass and aluminum rods are available as part of the PASCO Magnetic Force Accessory which includes additional equipment for use with the Variable Gap Magnet. The Variable Gap Magnet and Magnetic Force Accessory may be purchased together as the Magnetic Demonstration System.
