Hello again everyone sorry it’s been a while since last post or question, been working hard and had my nose to the grind stone, face stuck in many books along with heaps upon heaps of magnetic theory and EE lectures muhahahahaha.
Ok to the question, I have been having some trouble finding a formula for calculating the magnetic field of a diametrically magnetized rod, I believe I should use
Formula for the B field on the symmetry axis of an axially magnetised sphere magnet:
B =B r 23 R 3 (R+z) 3 B=Br23R3(R+z)3
Br: Remanence field, independent of the magnet's geometry (see physical magnet data)
z: Distance from the sphere edge on the symmetry axis
R: Semi-diameter (radius) of the sphere
The unit of length can be selected arbitrarily, as long as it is the same for all lengths.
This should work for most any point along the rod ?
