Hello everyone. I wanna use Comsol to calculate the magnetic force of an iron block (L1W1H1) under the influence of a permanent magnet (L2W2H2), and their distance change from 2cm to 3cm. How can I achieve this? Many thanks.

If you post your model then we might be able to troubleshoot, but if the instructions have been followed in the example above, it should work just fine.
