A current I=2 Amperes flows in a circular single loop coil of radius R=10 cm.

Question

(a) Evaluate the magnitude of the magnetic field (in Tesla) at a point P on the axis of the coil, and a distance z =5 cm away from the plane of the coil itself.

Now consider two N-turn circular coils of radius R, each perpendicular to the axis of symmetry, with their centers located at z=±l/2 . There is a steady current I flowing in the same direction around each coil, as shown in the figure below.

(b) Assuming the N=100, I=2 Amperes, R=10 cm, l=2 cm calculate the magnitude of the magnetic fied (in Tesla) at a distance z=0.5 cm from the midpoint between the centers of the two coil.

(c) Evaluate the first derivative with respect to z of the magnetic field calculated in part (b) using the same values for the parameters. Express your answer in Tesla per meter.

C) Calculate the second derivative with respect to z of the magnetic field calculated in part (b) using the same values for the parameters. Express your answer in Tesla per meter^2
