[Nfb-science] experiment with magnets

[Mike Freeman]

(1) Try a magnetized iron bar at least a foot long suspended from a string.
Yes, it will move but if the student touches gently from above, s/he should
get an idea where the magnet is pointing.

Alternatively, there used to be compasses like Boy Scout compasses that
could swing freely and, after a few seconds, be locked in place so they
could be felt without disturbing their alignment.

Hi all,

My student and I are conducting few science experiments these days and this
week the topic is magnetism. We want to do the experiment where the magnet
when suspended freely comes to rest in north-south direction.

My question to you all is whether there is a way to find out how the magnet
is aligned when it comes to rest. We cannot touch it since it starts moving
the moment we touch. How can the student know the alignment without touching
it?

Thanks much,
Shanthala
