Creating two Magnets with opposite Polarities

I want to create two magnets (Assume to blocks up and down with a distance from each other) that have opposite polarities so as a result they will repel each other. (see attached pic)
How can I do that?
Thank you.

Thank you very much, but your file doesn't open and it gives a message of "comsol muliphysics model file is damaged or not valid".
Would you please fix and send me again.
I appreciate it.

I have attached my sample, would you please fix and send it back, maybe in that case I would be able to open the file.
Thank you.

(1) you never defined your materials, and
(2) you did not include any volume of space around your magnets.
Both are essential before you can run your model. Every field region in the model requires material properties. And you must include plenty of space around your magnets, so that the fields can be computed within that space.

I built this model without any data so you can build yours, because I can't open your file maybe I will be able to open this file.
I need to learn how can I define opposite polarities in the magnets.
Please insert all necessary data in that model as you did in yours. (The same way)
Thank you very much

In the first model, I have defined the magnets and fixed the end of the rods ( Solid Mechanics).
And I want to see the two magnets attract or repel each other but it seems Comsol doesn't do the coupling automatically! coupling of Magetic and solid mechanics.
In the second one, I have put body forces to the magnets equal to the force that Comsol Estimates in Magnetic module.
Now my question, is there any way that comsol will automatically calculate the magnets repelling/attracting forces and put it in solid mechanics as BC?
Or the only way is that I have done in second model.
Thank you.

And I want to see the two magnets attract or repel each other but it seems Comsol doesn't do the coupling automatically! coupling of Magetic and solid mechanics. Because the rods don't deform.
In the second one, I have put body forces to the magnets equal to the force that Comsol Estimates in Magnetic module. But this can't be correct since I am adding the forces direction manually, so it is not dependent to the polarity of magnets.
Is there any way to do this automatically? coupling solid mechanics with magnetic modules and see the deformation of rods due to polarity of magnets.
Thank you.

have you gotten the answer because I stopped in this point also.
Thank you
