You are holding a compass 3.60 m from a longstraight electrical supply wire that is carrying a direct currentperpendicularly to the local direction of the Earth's magneticfield. Instead of orienting to any consistent "north" direction, the compass needle swings aimlessly no matter how you tilt or shakethe instrument. The strength of the Earth's magnetic field at yourlocation is 5.12×10−5 T. What is the magnitude ofthe current carried by the wire?
