How to model a permanent bar magnet in SimScape?

I'm using simscape to model a robot which drives a long a metal surface and adheres to it through the use of permanent magnets embedded in the wheels. I've imported my own geometry. Is there a way I can 'assign' part of the geometry as a permanent magnet?

Hi,

What is the meaning of the phrase "I've imported my own geometry"?

I hope referring to https://www.mathworks.com/help/physmod/simscape/lang/generating-custom-blocks-from-simscape-component-files.html may help you.

Hi Hari,

I haven't been able to find any equations to apply to a custom block given field strength and distance etc. I am hoping to add a permanent magnet that starts at a distance from a plane surface and see how the magnetic force on the plate gets stronger the closer it gets to the plate. Is it possible to use the magnetic foundation library to do this?

hi Rory,

have you been able to find a solution for your problem? maybe the answer on this 2 links can help on something. if you have found a different solution, could you share with us? im trying to model a simmilar robot
