first question..
A long straight wire carries a steady current of 250 A. Draw a sketch showing the direction of the magnetic field caused by a 0.01 m segment at a point 1.7 m from the wire and perpendicular to the segment. Also, find the magnitude of the field contribution at this same point by the small segment.
second question..
A magnetic field of 35 T has been achieved at a laboratory studying superconductivity. What magnitude of current would be needed to achieve this field at a point 0.05 m from a straight wire.
