  • Is there any material that can block a magnetic force ...

    So the short answers: No material can block a magnetic field. Lead most definitely has little to no effect on magnetic fields. If you want to block out magnetic 'force,' your best bet is to re-route magnetic field lines (lines of magnetic flux) around the object that is sensitive to those lines. Do this by shielding the object in a material ...
