Introduction
Use the Magnetic Damping Accessory to add drag to a PASCO dynamics cart. When the cart moves on an alumi-
num track, the accessory’s magnets generate eddy currents in the track, which cause an opposing magnetic field.
The resulting drag force is proportional to the cart’s velocity. The amount of damping can be varied by changing
the size of the gap between the magnets and the track.
This manual includes set-up instructions, three experiments (starting on page 3), and sample data (page 13).
Set-up
The Magnetic Damping Accessory attaches to a cart magnetically using the magnets built into the cart’s bumper.
If your cart does not have bumper magnets, install them before using the Magnetic Damping Accessory. (See
instructions included with your cart for bumper magnet installation.)
1. Remove the keeper plate from the Magnetic Damping Accessory and put it aside.
