The current in most electrical appliances is well above the levels the human body can withstand. The electrocution effect is increased if the appliance drops farther from the drain or if the water has more salt in it (such as due to urine or epsom salts). They also proved that devices (and probably by extension, sockets) with GFCIs are effective at preventing these electrocutions, as a GFCI-equipped hairdryer cut off on contact with the water.
The compounds in the pigments of most tattoos simply do not react to magnetic fields. Old pigments of the color black, which had iron in the composition, could cause some discomfort at most.
