Electromagnet Robot Retrieval Device

An Electromagnet is a magnet that runs on electricity. The magnet is made by coiling wire around an iron core. Once the magnet is made,it can be turned on by running electricity through the wire coil. Electromagnets have many uses. They can be used to pick up and move ferrous metals, such as iron. They can also be used to detect ferrous metals. This technology is used in metal detectors and in CAT scan machines.
Students will design a structure that can successfully navigate the cave and retrieve the robot (paperclip) using an electromagnet.

This Guide provides the instructor information on how to run the design challenge with alternatives for materials and test setups as well as information to help make the design challenge a good educational experience.

Electromagnet Robot Retrieval Device Video

The video conveys the societal impact of the student’s research that is the basis for the design challenge and will set the problem-solving context for students. The video also  leads students through the design process. It indicates materials available, states what the criteria are for success and any constraints.
