Other consequences
Bee-keeping:
Strong electric fields from power lines can charge the frames of beehives if these
are of metal. This can cause spark discharges that can seem disturbing to the
bee-communities. The bees can get aggressive, start fighting among themselves, and
can in extreme cases commit suicide by clogging the hives with wax.
Computer-PCs
Electric fields can disturb computers in the following ways: the picture
on the monitor gets untidy and/or disorted.
Electrical shocks:
The electric field from larger power lines can charge objects of metal - and people that
are isolated from earth by for example rubber soles. You don't notice that you are being
charged, but you will feel the discharge to an earthed object, like a shock - in the same
way as when you walk on a wall-to-wall carpet and grab a door handle.
Pacemaker:
Disturbances can occur from the current leakage from electric instruments, and in rare
cases from power lines. In the electric fields that develop under the largest power lines,
pacemakers can start to beat in a steady frequency.
This effect can feel uncomfortable, but is completely harmless.
