Danger, you're great! thanks for the effort! I understand what u mean now. but still, there can't be any interaction between all the 15cm. Thanks again, Shay

I'm not sure i understand what you are proposing.

The disk magnet will weigh with the load 400grams. It will be in normal environment (air). I can't use any mechanical approach, have to do it with electromagnets. Thanks again, Shay

I'm trying to pull the disk from 15cm away

Thanks Bob, I'm going to put an iron core in it. The disk is magnetized on it's flat faces. There is no other metal near the system. I'm going to cushion it in order for it not to brake, it's a disk with a diameter of 50mm and a width of 5mm. I still don't know how to calculate the...

Hello, I need to build an electromagnet in order to pull a disk magnet from a distance of a 15cm. I don't know how many turns and how large to make the electromagnet. I need it to be in the shape of a solenoid. What are the formulas needed in order to do this? Thanks in advance, Shay
