Direct Current

July 22, 2009 3:47 am | Electric Motors

You hold a compass 3.60 m of a straight line to supply long wire that is crossed by a direct current?

Instead of direct coherent whole to "north" direction, the compass needle profit, no matter how you tilt or shake the device. The strength of the magnetic field of the Earth at your location is 5.12 × 10-5 T. What is the magnitude of current carried by the wire?

B = μoI/2πr, I = 2πrB/μo = 2 * 3.14 * 5.12x10 ^ 7 = ^ -5/4πx10> obtained calc?
