video - Solenoid w/ Iron core
Purpose:To demonstrate ferromagnetic properties of Iron.
We have two sets of solenoid with iron core. The homemade green solenoid shown in the first two images and a newer red one in the third image.
Hints:The red solenoid is made by Ginsberg Scientific part# 7-1850-1. A black plastic tube of ID=0.80" is wrapped with copper wire to form a coil of 1-1/4" dia. by 4-1/4" long. The coil has 22 turns per inch, times 3 layers per turn to give a total of 300 turns. The iron core is 0.75" dia. by 6" long.
