Question Will a magnet cause an induced charge? Our particular application is using magnets with metal standoffs to support ECBs for masking. The magnets are "directional" in that most of the magnetic force is at the opposite end of the standoff. - Anonymous, Beaverton, OR
Answer Standard, permanent magnets should not be a problem in causing induced charges. If a conductive object travels against the magnetic flux lines then a current will be induced on the conductor (relative to the magnetic field strength). For standard, permanent magnets, this induced current would be in nano or micro amps. The exception would be for very high field permanent magnets or high powered coiled magnets, where there is a chance of creating a large enough magnetic field that could create sufficient currents and/or induced voltage spikes on nearby conductors (if they cross the flux lines). One example is an EMP from a nuclear detonation, so no worries.
