If the current in the wire increases, the amount of magnetic force produced by
the wire
A. increase
B. Decrease
C. Remains same

amount of mag etic force produced by the wire remains the same.

answer; the correct answer is technician a; ///100%good luck

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
