Hello Desiree,
You cannot delete a default physics node: you over-ride it by applying some other setting to the same entity (domain, boundary, edge or point). See Introduction to COMSOL Multiphysics manual version 5.2a, page 37 and 112 for more details. All manuals are accessed through the File > Help > Documentation menu.
Best,
Jeff

Okay thank you. I will try to see which node can best fit my model.

Basically I just want the magnetic insulation on the exterior boundaries (air). Which type of boundary condition is most suitable (I tried adding the magnetic potential boundary condition but I don't know the value of A) to remove the magnetic insulation from the all other boundaries. Additionally, I don't think perfect magnetic conductor boundary condition because I want current flowing through all other boundaries. I'm trying to understand the periodic (continuity and antiperiodicity) condition but am having some trouble. I'm just starting out with something simple like the model attached.

The last step in your geometry is "Form an Assembly". Why?
If you use "Form a union" all internal interfaces are continuously connected and the externals
have magnetic shielding as required.
If your really need the the assembly than you can a node "Continuity" and apply it to the "Identity Pair 1".

Thank you for your suggestion. A reason I used "Form Assembly" is that I thought it was needed whenever there were contacting surfaces. But all my geometry is stationary and defined correctly with the "Form Union" so I will go back to using that. Another reason I used the assembly was because in the actual model I am using, the "Form Union" kept showing an error. It was..."boolean geometry failed." I suppose I will just play with the repair tolerances and see if it works out.
