Today we did experiments with iron fillings and magnets, this is shown in the picture on the above post. We think that the Iron fillings are like younger brothers and sister, they follow you around!
We also did experiments in the difference between bar and ring magnets.
Paper Clips:
Bar=3
Ring=2* came off after a minute
Nail:
Bar=6
Ring=4
these measurements for the nails were not end to end, only 1 nail was touching the magnet though
How far off ground, to pull up paperclips
using horizontal ruler
Bar=3.3cm
Ring=0.8cm
