Welcome to The MIT Department of Physics Technical Services Group website.

About TSG
The Technical Services Group (TSG) 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. For more information on the MIT Department of Physics visit their website, or see MIT OpenCourseWare to download free course materials.

We provide support for most variants of 8.01, 8.02 and 8.03 classes in the form of:

  • Demonstration setup, execution and breakdown

  • Laboratory setup, execution and breakdown

  • TEAL classroom teaching assistance

  • General TEAL room support and maintenance

Additionally we occasionally provide some of the above services for departmental open houses, graduations and other special events.

Wire Loop Around a Solenoid (H 8)

Keyword: Transformer Action
A four-turn flexible coil is placed around a long solenoid. The solenoid is connected to 125 VDC at 5A. When the switch is closed a current is induced in the coil. The current is displayed on a center-zero projection meter. The switch is opened and the current shown is equal and opposite. The coil can be deformed around the solenoid and the readings will remain the same. The wire loops are then doubled around the solenoid and the demonstration is repeated. The eight-turn coil now yields twice the current.
