Subject: RE: e/m demo tube with Helmholtz coils


I just ordered a Daedelon today.
Tel-Atomic may be better, but the Tel-Atomic unit has many separate parts -
power supplies, cables, etc.
The Daedelon unit is self-contained.
I bought it for demo use. Some of the profs like to run into the stock
room 10 minutes
before lecture and grab equipment, so they wanted something that is "all
one piece".
Cenco and also I think Pasco make e/m apparatus. One of the Cenco units
looks to me
like a Tel-Atomic that Cecno markets.
