Magnetic field due to nuclear spin

Click For Summary
SUMMARY

The magnetic field due to a nuclear spin exhibits radius dependence as described by the equation B = -μ₀ μI / (2π R³). This relationship indicates that the magnetic field strength decreases with the cube of the distance from the nucleus, highlighting the inverse cubic law governing magnetic fields generated by point-like sources. The discussion references the HyperPhysics resource for further clarification on the topic, confirming that understanding this equation is crucial for grasping the principles of nuclear magnetism.

Hi all.

Can anyone tell me why in the equation of the magnetic field due to a nuclear's spin has radius dependence? How come?

B=-u0 uI / 2 pi R^3

(sorry about the typing, I don't know how to type a porper equation..)

Thanks in advance
