Non-Contact Force Kit

DEMONSTRATION OR ACTIVITY

Description

This kit provides sections of various pipes allowing students to experiment with non-contact forces like magnetism. As the magnet is dropped through the pipe the induced electromagnetic field slows the magnet and gives a noticeable difference in time to exit the bottom. Students can make predictions and experiments with different combinations of pipe size and material to get a variety of results.

Featured Trade: Electrical

Contributors: Warren Anderson, Josh Hill

Concepts: Lenz Law, magnetism, gravity, ferrous/non-ferrous metals, speed, rates

Located on the traditional lands of the Blackfoot Confederacy, Lethbridge College is committed to honouring the land from a place of knowing. We honour the Siksikaitsitapi as both the traditional and current Land Keepers of this area, and we welcome all First Nations, Métis, Inuit, and non-Indigenous peoples who call Blackfoot territory their home.
