core saturation with perm. magnets
core saturation with perm. magnets
(OP)
Hi, I am new here and magnetism is not my best side. I need an answer on the following:
question 1:
I have a "U" transformer form with a cross section of 85mm X 35mm, The saturation inductance is 1.56T (15.6 Kgauss) Now I want to put a permanent with a cross section of 85mm x 35mm between the end of the legs of the "U". What permanent magnet do i need to just saturate the metal of the "U" and how do I calculate that?
Question 2:
I need also to replace this permanent magnet with a electro magnet so that it shows the same saturation. how do i calculate the number of turns for the wire (dc and ac 50Hz)
Question 3 To saturate the same "U" but pulsed with 24v DC, how would I go ahead to calculate this.
It is important that the power use is as efficient as possible in all different cases. Can I change the power usage by changing the applied voltage for the same saturation?
This is a big slice of bread, But for you magnetic people this is nothing.
I thank you for the answer,
Willy

The elcetromagnet is simple physics. Amps times turns, times the right conversion factors.
In pulse mode you do the same, but the trick is knowing the peak current, and making sure that the pulse is long enough to get saturation.

What is the "the right conversion factors. Is this also the 15.6/12.5?
Thank you again.
