Magnétic Newtonmeter

The magnetic Newtonmeter is a tool to measure magnetic fields.
With this tool you can determine the force of your magnetic things.
It Will be very usefull in lab and when making eléctrical things as motors coils transformers etc..

You need to mesure ferrite mass and volume to have density
And need too, measure the surface of attraction
Mine have 8,3gram and 2ml=2cm³
Density is 4.15gr/cm³
I haven't attraction surface because It isn't plain needing a new one with scuare form mine have toroidal ring and is not canonical

The easy make is attach the ferrite to newtonmeter with a cord, plastic , nilon are the best because don't interfere with magnetic fields, I have done with Cooper cord, Cooper It is not magnetic and do the job.

Now it's time to test.
Go to tour lab and search for something you suspect it's magnetic, things as motors, transformers, coils, of course magnets and much more
I have get a magnet from a speaker
And take a lot of measurements,
It have mostly give measurements between 160 and 200gram of force in bigger force point I called magnetic pole center
You can use a compass to determine if is north or South pole

In my books there's no any magnetic newtonmeter and it's time to invest
Could be per example
Force of magnet: X gram/cm²
with a
surface of: S mm²
If it's valid it's a new manner to refer to magnets,
