Correct magnet positions

There are three magnets suspended from the slinky in the TC1. The first two are centred in the coil. Motion of these magnets from earthquakes are responsible for the induced current in the coil. The third magnet is suspended in the copper tube,  and dampens the system via Lenz’s Law.

Correct magnet positions. Click on the image for a closer-up view.

The pair of magnets in the coil, and the single magnet in the copper pipe should not touch the coil and tube, respectively, and their tops should be flush with the coil/tube, as shown in the picture.

If the magnets are not in the right vertical position, you can adjust the magnets by threading the screw on the lid up or down. If you need even more vertical adjustment, you can bunch or release rungs clamped in the lid of TC1.

If the magnets are not in the right horizontal position, adjust the knobs on the legs.


Why is my station’s snapshot not up to date?

If the screenshot of your station is not updating here, consider the following:

  1. Is your computer still on? In principle, it can’t be off is power is available: the bios should be set that the machine comes on after a power failure.
  2. Is your computer on the network? For macs, you can troubleshoot a wireless connection here, or trouble shoot in general from System Preferences > Network > Assist Me > Diagnostics.
  3. Is Jamaseis still running? Jamaseis should be in your startup menu, so that if the computer comes (back) on, so does jamaseis.

If the answer to the three questions is “yes”, check your log file (under the window menu in jamaseis). If you see an error that you can fix, great. If not, send us the log file and restart jamaseis.

Is the TC1 set up right?
