I've removed the "Examples of research groups using magnetic tweezers" section. Magnetic tweezers have become a common enough technique that a complete list would be very long and this is not the place for a directory. Related articles such as Atomic force microscopy and Optical tweezers don't have a similar section. Groups that have made significant contributions can still be identified from the references.

It seems the expression for the force due to the magnetic field on a small magnet here has an extra 1/2 factor compared to the magnetic moment page: https://en.wikipedia.org/wiki/Magnetic_moment#Force_on_a_moment Skarmenadius (talk) 12:33, 14 January 2016 (UTC)Reply

Magnetic Field decreases "roughly exponential"?

edit

In the "Magnets" section is says:

"The magnetic field strength decreases roughly exponentially with the distance from the axis linking the two magnets on a typical scale of about the width of the gap between the magnets."

Isn't is 1/R2 i.e. inverse square law?

Sure, in approximation one may say the above - but seems to be an unnecessary misleading simplification.
