Answer 1

Answer:

Given A current of 10 A is flowing from east to west in a long straight wire kept on a horizontal table. The magnetic field developed at a distance of 10 cm due north on the table is : Here horizontal plane I = 10 A, r = 10 cm = 10 x 10^- 2 m. Now for a straight wire towards north will be B = μo I / 2 π d.
