Product Overview
A practical alternative to the traditional suspended stirrup. This lightweight plastic carrier is mounted on a hardened steel pivot, allowing it to rotate freely in the horizontal plane. Designed for use with bar magnets or friction rods, the apparatus responds sensitively to magnetic fields or electrostatic charges.
Features:
-
Balanced plastic carrier rotates smoothly on steel pivot
-
Ideal for demonstrating magnetic or electrostatic interactions
-
Allows clear, stable horizontal movement without string suspension
-
Insulated rod minimizes interference from surrounding materials
