Microcubed¶
Microcubed computes the magnetostatic stray field of uniformly magnetised, axis-aligned cuboids and arrangements of such cuboids. The field expressions are analytical; no spatial volume grid or micromagnetic solver is required.
The library is particularly useful for:
permanent magnets with cuboid geometry,
segmented approximations of more complex bodies,
fast parameter sweeps outside magnets,
field gradients for force, sensor, and magnetometry applications,
reproducible comparisons with finite-difference programs such as OOMMF.
Important
Microcubed does not solve a magnetic equilibrium problem. Magnetisation, position, and geometry are inputs. Domain formation, hysteresis, exchange, anisotropy, and magnetisation dynamics are outside the model.

Quick example¶
from microcubed import Magnet
magnet = Magnet(
size=[500, 300, 50], # nm
center=[0, 0, 0], # nm
magnetization=[0, 0, 1.0e6], # A/m
)
B = magnet.Bfield([0, 0, -150])
dB = magnet.dBfield([0, 0, -150])
print(B.shape) # (3, 1), T
print(dB.shape) # (3, 3, 1), T/nm
