BATMAN - that looks like a really nice mock-up you have there.

Is it really built?

It looks to me like it's missing a couple of Rods - or is it supposed to?

Holy BATZILLA  your  a monster BATMAN  is this a preview of things to come?   Chet

[exxcomm0n]

For verification purposes.

Materials used:

3 3/16"- 4mm X 1/2"-13mm cylindrical neo-mags N42 rating I think.
Formica table top on 3/4" (30mm approx.) particle board
Plastic magnifying ruler 12"

EDIT2
No rods were used, only the mags.

==== is the magnet.


1.) Repel action @ 4cm, repelling to 4.5cm   = 45mm
        -====+        +====-
      0.7cm 2cm   6.5cm    7.8cm         

2.) Attract  action @ 4.6cm    =  46mm
        -====+        -====+
       0.7cm 2cm   6.6cm  7.9cm

3.) Repel @ 5.4cm , attract @ 6cm for repel = 54mm/attract = 60mm
        -====+           +====-                     +====-
      10cm 11.3cm    16.7cm  17cm              23cm   24.6cm

Looks like cumulative effort is a good thing.

EDIT
Fixed metric measurements.

Larry:

Thanks for doing this test Larry.  It proves the point that Archer first started with.  magnets are not as strong in repel as they are in attract.  the added fact that the two forces together creates more than their independant tests should allow, gives us some very interesting data.
so much for equal and opposite forces, eh?

It would appear that attract is 10% stronger than repel, and used together they are 30% stronger than you would expect.
Can anyone else back this up?  I'm at work right now so I can't, but will try tonite, and post results.


ciao,  Dirt

First I showed tests earlier in the thread that showed attract and repel were the same, I marked the distance one magnet attracted to the next then put the repel side at that mark and it still repeled infact if you put the repel to either side of the magnet and not dead straight on the repel even repels from further away then the attract, does that make repel stronger NO just its flux lines reach out further from the sides.
Second with a setup like that how do the magnets release from the attract, no matter how you spin it you still have to deal with the repel comming in and the attract comming out.
If attract is closer then repel then attract will pull repel in, if repel is closer then attract then repel will push attract out, if there both the same they counter each other.
To move a rod up and down would mean the attract is closer to its magnets and the repel is further away from its magnet, this would mean you still have the sticky spot comming out of the attract and a wall to break, the opposite the other way so you still have the sticky spot comming into the repel and a wall to break.
Nothing has changed that.

PS your talking distance here not strengh, strengh is how much force they both have from the same distance away, distance is how far the lines of flux reach out, the measurements done on the test here are for distance or how far the lines of flux reach out not strengh.

You have obviously been listening to Archie too long.

"Equal and opposite" doesnt mean a magnet will act equally in repulsion as it does in attraction, just like you probably can't pull a sofa as easily as can push it.

E & o means that two bodies acting upon on each other exert forces equal an opposite, respectivly.

Two magnets in repulsion repel each other equally and in opposite directions; you push on the sofa with the same force the sofa pushes back on you.

Equal and opposite.
