AI Thread Summary
Devices to measure the force between magnets include simple force scales, piezo crystals for precise measurements, and spring scales. The force varies based on the magnets' geometry and relative positions, but constraining their motion can yield accurate readings. Using a tube to hold bar magnets allows for effective measurement with a spring scale or load cell. An alternative method involves hanging weights to determine the force required to break the magnetic grip. Understanding these measurement techniques is essential for accurate assessments of magnetic interactions.

Is there any device to measure the force between two magnet?
 
Physics news on Phys.org
The force between two magnets depends upon the geometry of the magnets, and their relative positions:
http://en.wikipedia.org/wiki/Force_between_magnets

But if you can constrain their motion - put two bar magnets into a tube - you can use a simple force scale to measure the push/pull. For really close work you would use a piezo crystal, but an ordinary spring scale will work.

For example:

Pull spring scales: http://www.globalindustrial.com/g/packaging/scales/Dial/spring-scales-99102

Or a load cell: http://www.futek.com/product.aspx?t=load

Or you can just hang some weights ... and see how much it takes to break the magnetic grip. Slip something between the magnets to control the spacing.

Thread 'Motional EMF in Faraday disc, co-rotating magnet axial mean flux'

So here is the motional EMF formula. Now I understand the standard Faraday paradox that an axis symmetric field source (like a speaker motor ring magnet) has a magnetic field that is frame invariant under rotation around axis of symmetry. The field is static whether you rotate the magnet or not. So far so good. What puzzles me is this , there is a term average magnetic flux or "azimuthal mean" , this term describes the average magnetic field through the area swept by the rotating Faraday...

Thread 'Why measure the speed of light in one direction?'

It may be shown from the equations of electromagnetism, by James Clerk Maxwell in the 1860’s, that the speed of light in the vacuum of free space is related to electric permittivity (ϵ) and magnetic permeability (μ) by the equation: c=1/√( μ ϵ ) . This value is a constant for the vacuum of free space and is independent of the motion of the observer. It was this fact, in part, that led Albert Einstein to Special Relativity.
