Hi,
I would like to plot the magnetic field intensity for a given loop geometry, in 3D. Specifically, I want to study the magnetic field distribution for inductive coupling antennas (RFID Low Frequency applications, within the order of 120 kHz, the loop antenna behaves basically as an inductance) when a current moves throught the loop.

Hi @MRR
quiver and contour came into my mind when you mentioned about field intensity and current loops.

What do you think?

Hi @Sam Chak,
Thank you, but what I want is actually to get the magnetic field distribution given a specific wire geometry.

There should be a mathematical relationship between the wire geometry and the magnetic field distribution.
If you can provide that and a sample wire geometry, then some physicists who are good at MATLAB maybe able to guide you.
