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 Nturn 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

URGENT !! PROBLEM 2 !! D:

physics  FLu, Wednesday, April 10, 2013 at 3:46pm
Problem 2 is answered now Ruben, look at my profile. Do you have by any chance Problem 3 c) second part?
tesla in square meter

physics  Luiis, Wednesday, April 10, 2013 at 5:27pm
The second part in c) problem 3 it's tricky ... i didn't got yet. ):
Please angle in the Aurora Zone ??

physics  FLu, Wednesday, April 10, 2013 at 5:29pm
That is easy Luis it is 18.
Please let me know anyone who cracks second answer part c)?
thanks

physics  Mag, Wednesday, April 10, 2013 at 5:32pm
Please answer second part tesla in meters problem 3) c) !

physics  Luiis, Wednesday, April 10, 2013 at 6:51pm
YEAH I GOT IT PROBLEM 3 c) secnd part 0.687332867 !!!
SO PLEASE PROBLEM 4 (b) ??!!!
Hurry up i got 10 minutes to check !!!!!

physics  FLu, Wednesday, April 10, 2013 at 6:54pm
Thanks Luis, it is below!
4)b)
(pi*B^2*L^4*omega)/R
