It is always nice to have all the tools and measuring equipment possible but if you are on a budget then “second best” sometimes has to be the case.

So when I wanted a Gauss meter all I could afford was something homemade. All I needed to know is in the very excellent write up on the net…

It is very limited in range, non calibrated, not worth a hoot on neo’s but a godsend for those moments when you wonder what is going on. Here are a couple of pictures…

Another nice help Ron. Thanks.

Does your coil cause acceleration? If so, can you scope the Gauss meter output and the coil amps at the same time during acceleration.

I_RON,

no, no, no. I just talk about one set of three magnets for this moment.

The process I have in mind is this :

the first magnet aproaching the coil is South followed by two succeeding North-Magnets  ( S -> N -> N ) . In this way the sharp decline in the mentioned picture is delayed beyond the TDC-Line. My idea it to move the peak of the voltage ( which also means the power- and force-peak ) to the right side of the TDC-Line  As I said : I might be totally wrong.

Just think about what this would mean then concerning the forces acting aginst the prime mover .

EDIT:
the following is incorrect in that all coils exhibit this behavior when shorted

Larry, Kator,

The following is a bit of a bomb shell, I was looking for phase shifts but was not expecting a 180 shift!

Same as before, the trigger magnet is directly behind the north out facing magnet and is the blue bottom trace. it is there for reference and the "T1" marker is set to TDC. The difference now is the previous posts were of the voltage, these shots below are Gauss.

The first pic is a classic showing the flux build up and peaking at TDC, just what one would expect. This is with the coil open. The next pic shows the flux does a 180 when the coil is shorted.

Now what I expected to see was something like the Hall_HC pic with the "flux" displaced side ways...

Here also, for reference, are pics with a 1k2 and 100ohm load.

The core is 95 mm long the coil is 57 mm long.
The HC coil was 187 turns @ 1.2 ohm

This is an interesting occurrence and I do hope several pickup on this and do similar tests. I have never come across this before and seek verification.
