Transient simulation output doesn't match input

Hi

I'm simulating a 2mm radius magnetic loop excited by a transient current and surrounded by a 10cm air sphere, in time dependent study.

I've interpolated a gaussian current input from several points along time from 0 to 12E-8 (attached file).I'm exciting the loop using magnetic field (mf)'s external current density node along phi (cylindrical system) with "1[A]*int1(t[1/s]))/0.00000019635[m^2]". Note that I've declared "t" as a variable in seconds.

After running the time dependent simulation in "range(0,1.0e-8,1.2e-7)", I wanted to plot the magnetic field of a cut point located at 50mm (x,y and z) along time using the 1D point graph which, basically, must result in a gaussian curve too.

The problem is that I get a very different plot (not gaussian at all) with weird magnetic field values. Another problem is that the curve of the magnetic field with z component (attached) is different from the magnetic field, y component (attached) and also the x component, which I think should have been more or less the same according to my researches.

I tested with a sinusoidal excitation and it's the same case.

So, could you please tell me what's wrong with my simulation. Please help, it's means a lot to to me .

Thanks very much.
