How to obtain the magnetic force??
Hi ,
I didn't have any experience to design coil and permenent magnet .
Now i have to do one project using coil and magnet NdFeB. But i haven't got the maximum force. (need maxi force between 1300 to 2500)
I am doing the below procedure. Is it correct?
using DC supply 48V,
known value :core internal and external diamer, length
1. choose the wire size (From AWG spec)
2. calculate the number of turns / layer (turns/inches * core length)
3. calculate the number of layers (turns / inches * core thickess)
4. calculate total no of turns (Step 2 * Step 3)
5. calculate the wire length (using AWG spec's : ohm / km)
6. calculate the resistace and current.
7. calculate the B using (B = u0 * N*I/L)
8. calculate Force using (F=B*I*L(length of wire)).
Do i need to consider NdFeB magnet mass and B in this calculation? How can i get the force??
Anybody helps me?
Thanks in advance for the help.
