Question by hhhhhh: Physics Question about a wire and coil and the number of turns the coil makes.
The radius of a coil wire with N turns is r=.22m. A clockwise existing of I coil= two. A flows in the coil. A lengthy straight wire carrying a current I wire= 31 A toward the left is located .05 m from the edge of the coil. The magnetic field at the center of the coil is zero tesla. Figure out N, number of turns.
