Activity 3: Quantitative Problem Direction: Solve the problem as directed. Write your answers on a separate sheet of paper. You may also consult your Physics teacher. A coil consisting of 100 circular loops with radius 0.60 m carries a 5.0-A current. (a) Find the magnetic field at a point along the axis of the coil, 0.80 m from the center. (b) Along the axis, at what distance from the center of the coil is the field magnitude 18 as great as it is at the center
