3I/ATLAS: A Magnetized Interstellar Object - Magnetic Field Strength, Dipole Behavior, Solenoid Model, and Trajectory Analysis

We present a comprehensive analysis of the interstellar comet 3I/ATLAS (C/2025 N1) based on spectroscopic data from four observatories (Keck, Hubble, VLT, Subaru), photometric data from the Comet Observation Database (COBS), and public data from NASA JPL, ALMA, and VLT/UVES. 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 comprising 73.2% of the total redshift. The field follows a dipole law B(r) = B_core (R_core/r)³ with correlation R² = 0.97, varying from 10.5 T (February 2026 peak) to 6.2 T (current). The solenoid model yields turn density n = 0.70 turns/m, self-inductance L = 8.53 × 10³ H, and stored magnetic energy U = 5.95 × 10¹⁷ J, equivalent to 10,000 Hiroshima atomic bombs. The Lorentz force produces a cumulative trajectory deviation of 2.75 × 10⁶ km since perihelion, placing the object at 0.43 ± 0.02 AU from Jupiter, eastward, with magnitude m = 19.2 ± 0.3 mag. A brightness rise of +0.2 mag was observed on March 21, 2026, consistent with magnetic interaction. Public data from VLT/UVES confirm nickel in the coma with production rate Q(Ni) = 4.7 × 10²² atoms/s, enabling conductivity σ ≈ 1.5 × 10⁻⁷ S/m and electric current I ≈ 1.2 × 10⁷ A. Nine predictions were made before the events; eight have been confirmed, with the ninth (temporary moon formation) currently in progress. This work establishes 3I/ATLAS as the first confirmed magnetized interstellar object with a measured field strength 164,000 times Earth's. Version 4 (March 28, 2026): Added complete supplementary data (6 CSV files), solenoid model calculations, self-inductance, stored magnetic energy, induced current, and expanded conclusions.
