Max. breaking current: 3 A.
Base plate: 120 x 90 mm.
Allows a rotary motion sensor to mount on a Dynamics Track and act as a high resolution bi-directional Smart Pulley.
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.
Replacement test coupons for the Stress/Strain Apparatus.
Designed to measure magnetic field with three selectable ranges of +-1000 gauss.
An extra 3-step Pulley for PASCO’s Rotary Motion Sensors.
