Oudin coil would also likely work. Buy a full spool of #24 enameled wire
of around 10k' long. Remove as much of the middle of the spool as
possible to make the hole larger. Put in the largest soft iron core you
can fit. Flatten a 10' section of 1/4" copper tubing and wrap it around
the entire spool. Take care that the copper coils do not touch or
separate with paper. connect the ends of the copper pipe to the 120V
60Hz power supply near the circuit breaker. The resulting magnetic field
will obliterate radio and tv transmissions for about 2 miles.

Hook that up to a tesla coil for some real fun.
