如何计算检测线圈上的感生电动势?

yswlmike

在交变的电磁场中,想用一个线圈去检测某个空间位置的磁场强度,一般可以在该位置放置一感应线圈,并通过检测线圈上的感应电动势的大小来计算磁场强度.这样一个感应线圈在ANSYS中一般不给模型的,而是线计算出B,再计算感应电动势,但如果不这样做,而要直接给出线圈模型(闭合,有电阻),直接求线圈上的感生电流从而计算出电动势,请问高手们,能这样做吗?

here i have a very old code wriitten by ANSYS top guys, hope these codes help.

COIL_EMF
Bill Bulat (CSI)
===================
Used to report per-turn EMF induced in predefined closed loop paths.

EMF1
Mike Yaksh (NAC Int'l)
===================
"Example of computing the emf in a coil for a 2D planar model. The last thing on the screen
will be a plot of the EMF. This macro cycles thought difference positions. Some more
details on the CEs can be found in the EMAG training guides. One of the problems in the
training uses the CEs for a sliding type application. Hope this helps."
Please see updated EMF2 macro.

EMF2
Bjoern Possner (VEM motors GmbH)
====================
Updated Mike Yaksh's EMF1 macro.
"The older version of the EMF1 macro doesn't account for the speed or frequency with which
the magnet is being mooved under the coil. In addition, this macro has a correction with
the 3600rpm value."

我也想做一个接收线圈和一个发射线圈的例子，请高手多多指教

使用CIRCU124，可以直接提取EMF

你做出来了吗，能不能介绍一下。不胜感激！
