Vernier Cart Oscillator

Closeup of the cart with attached connector.

Description

The demonstrations:9_equipment:vernier_track: is set up at an angle, resting on a horizontal bar attached to a lab stand. On the same lab stand another bar is attached which serves as an attachment point for a spring. The other end of the spring is attached to one of the carts that go with the track using the attachment connector made for this demo (pictured). The connector has a steel part onto which a large neodymium magnet can be placed. Since the track is made of conductive but non-ferromagnetic aluminum, eddy currents are generated by the magnet when the cart is in motion that produce a damping force which is linearly dependent on velocity.

Purpose

Demonstrates damped simple harmonic motion. The magnet can be adjusted to be closer or further away from the aluminum vernier track, thereby allowing for the level of damping to be adjusted from a low value (no eddy current damping, just friction) to a higher value.
