Question

Dipole to Dipole interaction
(Attraction/repulsion over a distance)
Is that work being done by the magnetic field?
Can a magnet do work on another magnet?

Answer 1

I said yes.
Magnets can do work, since they apply a force on another magnet within a distance.
And also, that a magnet to magnet field interaction is completely different than a magnetic field with a point charge interaction...
Work in tat case based on Lorent'z law is zero from the B filed...

Answer 8

Magnetic dipoles have work done on them by a magnetic field by having torque produced as well as a transnational force..

\[torque=M×B \]

(vector product) where M is the magnetic moment of the dipole

However the magnetic field of a magnetic dipole is the same form as for electric charges. i.e.

\[B _{r}=kMCos(Θ)/r3\]\[B _{\Theta}=kMSin(Θ)/r3 \]

Where Fr is the radial component of the field and\[B _{\Theta}\] Is the component in the direction of the angle between the radial vector and the mag moment vector. Two interacting and free dipoles will twist one another around and pull themselves together.

Answer 9

@gleem and that twist and pull is the force of two of the magnets doing work.
And based off of multiple rules it shows that indeed they do work.

Thanks. @gleem

Answer 10

Of course magnets do work!
What explains the idea of having them attracting/repelling each other? And also flipping a whole magnet's direction 180 degrees so it can align its self with the other magnet.

A magnet can Move/Stop/Accelerate/Decelerate another magnet.
That is work being done my friend in all cases.

Answer 11

ofcourse it does work

if you bring one magnet near the other, it puts a force on the other magnet.. (repulsive or attractive) and displaces the magnet.. so yes it does work

Thanks!
