MIT Department of Physics Technical Services Group

The Technical Services Group at MIT's Department of Physics provides technical and teaching support for undergraduate courses at MIT. Our many rooms of physics demos, accumulated over the past century, display subtle physics concepts ranging from electromagnetism, to kinematics, to optics.

The undergraduate physics courses at MIT include lecture courses, as well as the Technology Enabled Active Learning (TEAL) studio classroom courses. Click here for more information on the MIT Physics Department, or see MIT OpenCourseWare to download free course materials.

Exploding Wire

Exploding Wire

Added 1 year ago | 00:01:14 | 2335 views

A 100uF capacitor is charged to 3kV (450 joules) and then discharged through a thin iron wire, causing it to explode.

DC Motor

Added over 1 year ago | 00:01:17 | 2157 views

A DC current is sent around a wire loop that is free to rotate. The current causes the loop to feel a torque in the presence of a magnetic field. Switching the current when the loop flips over allows it to continue accelerating, demonstr...

Refraction & Total Internal Reflection

Added 2 years ago | 00:01:53 | 4213 views

A beam of light from a helium-neon laser is directed at a tank of water and is refracted as it enters the water.  The outgoing angle of refraction is smaller than the incident angle.  Next, the laser is directed from below the ...
