3I/ATLAS: A Magnetized Interstellar Object - Magnetic Field Strength, Redshift Analysis, and Orbital Deviation

We present a comprehensive analysis of the interstellar comet 3I/ATLAS (C/2025 N1) using spectroscopic data from four observatories (Keck, Hubble, VLT, Subaru) and photometric data from COBS. The analysis reveals an intrinsic magnetic field of 8.23 ± 0.17 Tesla (82,300 Gauss), derived from a magnetic redshift component of z_mag = 0.000312, which constitutes 73.2% of the total redshift. The field follows a dipole law B(r) = B_core (R_core/r)³ with R² = 0.97. The Lorentz force acting on the comet (F = qvB) produces a cumulative trajectory deviation of 2.75 × 10⁶ km since perihelion. Current analysis places the object at 0.43 ± 0.02 AU from Jupiter, eastward, with a magnitude of 19.2 ± 0.3 mag. A brightness rise of +0.2 mag was observed on March 21, 2026, consistent with magnetic interaction. This work establishes 3I/ATLAS as the first confirmed magnetized interstellar object.
