Calculate Magnetic Force
Hello,
I am the new one to design of magnetic cylinder.
One of this portion, I used magnetic coil and NdFeB magnet. I need to get the maximum force (nearly 2000N) for this magnet. But i didn't get the force.
I did this procedure. Correct????
For coil, external , internal and length are constant.
Step 1 i choose the resistance and diameter of wire from AWG
Step 2 calculate the numbers of spirals and maximum length of wire to use
Step 3 Got the Resistance using AWG scale (ohm / km)
Step 4 Got the current
Step 5 Calcuate the flux density B using (B= µNI /L)
Step 6 Calculate the Force using (F= ILB)
But the force is too low when using the above procedure.
Pls suggest to me.. The procedure is correct or not???
How can I get the maximum force and do i need to consider about NdFeB magnet's Br??
Thanks
