The elementary magnetic dipole of the proton has the value $-9.28*10^{-24}JT^{-1}$ (NIST).
The elementary magnetic dipole of the antiproton also has the value
$-9.28*10^{-24}JT^{-1}$.
Their magnetic fields are identical. The protons and antiprotons electric fields are equal in magnitude.
<aside> 📌 Presumtion: The annihilation of proton and antiproton as well as of electron and positron is based on the identical values of the magnitude of the electric charges and the magnitudes of the magnetic dipoles. ↓9↓
