Is there any material to resist magnetic field lines?
How about superconductors? How do they resist magnetic fields?
Superconductors can resist magnetic fields by exhibiting the Meissner effect. When a superconductor is placed in a magnetic field, it generates a counteracting magnetic field, which cancels out the external field within the material. This can make the superconductor appear "invisible" to magnetic fields.
