Hej!
I made magnet with two pole one north and south alone z axis... I also define one ampera law -500000 (negative shows south along x-y axis) and other ampera law +500000 (positive shows north alone xy axis) ...

I cannot see the field alone the sphere i do not understand.. but its running perfect

I want to know did i define correct + for north - for south

I am looking forward to your mail

Best Regards,
Mehdi Khan

Hi
I believe COMSOL has a issue with their site (disk full ?) when I try to download your file I get a 0 byte copy ;)
Try to upload it again later

Good luck

Hej Ivar

Upload the file again..


Now i feel i am doing correct ... I define ampera law alone x -y axis magnaization +35000 for north and -35000 for south...

My simulation are working but i cannot see magnetic field in the middle I want to se B=magnetic flux density in the middle.. like in arrow 3-d . I want to see field arround magnetc

I feel i did almost correct. Maybe i did minor mistakes

Can you please check and remove the error ... Or tell me how to remove it

Best Regards,
Mehdi Khan

Hi

I'm still getting 0 bytes when I try to download yours there (but it worked for another thread) will try another mirror site ...

Nope same stuff on .eu as on .com (+ some Application error pages from the site) Xmas effect ;) ?

Have you tried to download your uploaded files ?
