Explanation:
The magnetic field due to current in a straight thin wire, 
, is given by
where 
is the permeability of free spave with value 
and 
is the distance from the wire.
Substituting the values from the question,
The answers are 3.3kWh, 1.2kWh, and 120kWh.
Multiply the amount of kW used per hour by the amount of time it was powered and you receive your answer.
