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

Anyone for second part of part c) Tesla per metre square?
second part for c) Tesla per square meter please?
tesla in square meter
Please angle in the Aurora Zone ??
Please let me know anyone who cracks second answer part c)?
thanks
SO PLEASE PROBLEM 4 (b) ??!!!
Hurry up i got 10 minutes to check !!!!!
