THE PHYSICS
A closer look.
Dipole interaction forces follow the gradient of their magnetic potential.
F = ∇(m·B)
G is the gravitational constant, M and m are masses, r is separation, c is the speed of light, and b is impact parameter where applicable.
What you can learn
- Compare parallel and reversed magnetic axes
- Toggle magnetic forces independently of field display
- Drag sources together and inspect field superposition
Default bodies
Two 1 kg model dipoles, radius 0.2 m, polar field 0.01 T
GRAVITATIONAL FIELD · ILLUSTRATION
Prescribed-spin vacuum dipoles; rotational torques and plasma are excluded.
Space fabric illustrates gravitational influence; it is not a numerical solution of the full Einstein field equations. Visual sizes can be enlarged independently of physical collision radii.
