Demonstrations are cataloged according to PIRA Bibliography

PLEASE REQUEST DEMOS WELL IN ADVANCE

Due to Physics Building renovations, the lead time to set up demo requests has increased due to the need to transport equipment across campus. Please be kind and let me know well ahead of time what you need.

Flash Bulb Coil

Purpose:

To show that current is induced in a coil when the magnetic flux through the coil is changed

Procedure:

Insert a new flash bulb in the socket and arrange the reflector so that it is facing the students. Slowly insert the magnet into the coil and pull it out quickly. The bulb will flash if the magnet is removed quickly enough.

Hints:

Watch your eyes it's bright!!
