Electric fields are created by differences in voltage: the higher the voltage,
the stronger will be the resultant field. Magnetic fields are created when
electric current flows: the greater the current, the stronger the magnetic
field. An electric field will exist even when there is no current flowing. If
current does flow, the strength of the magnetic field will vary with power
consumption but the electric field strength will be constant. The key is not in
grounding the tank, but attaching all the appliances to a ground fault interupt,
and in eliminating the offending aplliance.
