Replacement Spheres and collars for the Gravitational Torsion Balance (AP-8215A). Designed to convert to Tungsten while maintaining the proper large sphere dimensions.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
A 400 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
Allows mounting and changing of distance between field coils and is used for studies in electromagnetism.
A 2000 turn wire coil on one end of a wand that has two terminals at the other end to accommodate banana plug contacts, permitting easy connection of an electric circuit.
A 200 turn wire coil on a bobbin that has a base with three terminals that accommodate banana plug contacts for measuring current or voltage. Can be mounted on a Helmholtz base.
Combines features that significantly improve the ease of setup, the durability of the Torsion Band and the quality of results. In the newer models the spheres are tungsten rather than lead.
Designed for experiments involving low light level conditions. ScienceWorkshop version.
Designed to allow the use of a force sensor as a balance.
Allows the students observation of velocity of drop rising in an electric field, then permits calculation of the force on the charge carried by the oil drop.
