The MƒA Thursday Think Speaker Series brings accomplished speakers who dive into cutting-edge topics in STEM education to MƒA. These talks, held once a month throughout the school year, invite MƒA teachers and the general public to learn and engage with these thought leaders and professionals in mathematics, science, and education.

Nikola Tesla was just 21 years old when he created a device that would transform the world. Today, this device is everywhere—in the bathroom, bedroom, living room, and even the garage. Your kitchen likely has at least five of them. What is this revolutionary device? The AC induction motor. 

Considered to be Tesla’s greatest invention, the AC induction motor is one of the most reliable, efficient, and widely used tools today and the primary reason homes worldwide use AC current. Invented in the 1800s when other motors used brushes, this motor transfers power wirelessly, making it the most durable spinning device on the planet. 

In this talk, tinkerer, teacher, and engineer Jeremy Fielding will teach us how induction motors work, highlighting the role of electromagnetism and making them come alive with props easily transferable to the classroom. The talk will be followed by a hands-on opportunity for teachers to explore, play with, and build their own induction devices.
