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.

DC Motor
Added 1 month ago | 00:01:17 | 295 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 10 months ago | 00:01:53 | 2858 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 ...

Helium introduced into a resonant cavity, including the lungs of the demonstrator, will increase the frequency of all pitches originating in the cavity. This is because the speed of sound in helium is greater than the speed of soun...
Bimetallic Strip
Added 10 months ago | 00:00:47 | 2049 views
A bimetallic strip (12" ) of iron and aluminum is vertically fixed at one end to a board. The top end has a pointer that is free to move. The bimetallic strip is straight at room temperature. When heated with a blow torch, the strip curv...
Magnetizing and Demagnetizing an Ir...
Added 10 months ago | 00:01:37 | 2488 views
An iron bar is used to try to pick up some paperclips or thumbtacks. It is not able to do this because it is not magnetized. The rod is placed in a long solenoid and DC power applied. The rod becomes magnetized and is able to pick up som...
