Also,
Changing the permeability of the core material value in the second, U shape core formula has only a very small effect. (For example changing the core permeability from 50 to 1000)
from
(60 * 0.001) / ((0.0152 / 50) + (0.0008 / 0.0000012566)) = 9.4244955 × 10-5
to
(60 * 0.001) / ((0.0152 /...
Thanks Skogsgurra,
Yeah, I originally assumed that the "gap" in the first formula was accounted for by multiplying the core permeability by the free space permeability (50 * 0.0000012566) which I thought represented when the magnetic field travels from one end of the rod to the other. Now I am...
I am interested in calculating the magnetic field strengths of electromagnets with a couple of different core geometries, and I have been making some calculations that I think have gone wrong somewhere and I was just wondering if someone could kindly point out where/how I have made a mistake.
I...
Hi everyone,
I am interested in calculating the magnetic field strength produced by an electromagnet with a core shaped like an O that forms a closed magnetic circuit, shown in the image that can be seen here -...
