HEllo everyone, Firstly, let me introduce my self, i am moel. Right now, i am busy with doing some research about earth leakage detection unit. In order to know the behavior of the electromagnetic relay that i use, i made a 3d modeling of it. When i want to load a current to the coil, the difficulties appears. I could not find a way to assign the whole body of the coil (so far only a planar area that can be signed). So, i would like to ask anyone's help. If someone know about it, please share some with me. I would be very thankful before. nothing is impossible, moel.
