current loop simulator

Hi,

Has anyone done any simulation on the current loop in HFSS? Is it possible to upload the file?

Thanks.

calculating current in hfss through a loop

What file do you mean?

The HFSS file for current loop simulation.

I don't have such projects actually. But probably I can do it in MoM. What do you need to calculate? Field radiated by impressed current in free space?

#### lokeyh

I want to simulate the magnetic field (x-, y-, and z-component) at a given position for a current loop.

If you can publish more information - current loop parameters (geometry, values), field probe poisition and frequency range you are interested in it would be possible to discuss solution more effectively.

The loop has a radius of 10cm and a sinusoidal current (100 Hz) with r.m.s 1A will pass through the loop.

The loop is situated at the origin and I want to find the magnitude of the x-component of the point (0<= x <= 50cm, y = 20cm, z = 20cm) in HFSS.

I have simulations in HFSS but I cannot get the magnetic information I required. So I am asking if anyone has done any previous simulation.

Hopes this clarifies the problem.

Thanks.

OK, and the loop is situated in origin in XY or YZ or XZ plane?

#### lokeyh

It is on the XY plane.

do not place current source in series. you will get an inaccurate result.

I have simulated this in EMC Studio. Please see results in attached pdf file. Is this what you have looked for?

Hi, this is the result I am looking for. Thanks. But it would be good to have it in HFSS as that is the only software available to me.
