Question

Does this make any sense?
(MAGNETSIM)

Answer 1

If you check the "pull force"
the rate of force of attraction between two magnets at 0 distance.
As you go far away the force decreases to 0. As you come closer to the magnet, the force 21 lb of force!

This "pull" force represents both the attraction and repulsion rate of the magnet.

Answer 2

you can use this calculator to understand what I mean.

Answer 3

plug in 0.8125 for dia.
plug in 0.25 for thickness.
plug in distance is mm( what ever you like)
and a certain force number will apear.

What do you all think?
Makes sense?
And yes! There are 3 set ups! "cases" in each case there is a certain rate of force.

So what do you all think of this.
Is it accurate?

Answer 7

That pull force is the rate of attraction and repulsion of the magnet DD4.
So can I relie on that calculator to give me an output value to use in calculations that requires attraction/repulsion etc...

Answer 8

I don't quite understand what you're asking...

Answer 9

Pull force from the site...
Does it make sense?
DD4 magnet typically can attract with that force.

Answer 11

@Jemurray3 for some reason I can't even ask the right question.
But what does pull force in that site mean to you?
Does that represent the attraction/repulsion force of the magnet to other magnets?

Answer 12

That appears to mean that it would take about 20 pounds to pull two of those magnets apart.

Answer 13

I contacted the manufacturer
They told me that the magnet can pull with 20 pounds of force and repel with 20 pounds of force at a distance of 0.
Because using that calculator would also show the repel force.
@Jemurray3 thanks for your help.
