| description | Detecting marine vessels can be achieved by analyzing the magnetic disturbances they create within the Earth's magnetic field. This research introduces a laboratory-scale Drive-in-inspired system, designed and built using Helmholtz coils, a solenoid, and a linear array of magnetic sensors. To assess the effectiveness of a deperming procedure, two samples made of ST37 steel – a plate and a hollow cylinder – were utilized. ST37 is a high-strength, low-carbon steel widely used in marine and construction applications, and it is a typical soft hull material for submarines. To isolate the magnetic signature stemming from the samples' permanent magnetization, their induced magnetic signature was initially characterized through both experimental measurements and simulations using COMSOL software, with a strong correlation observed between the two. The deperming process was then implemented using the Deperm-ME method, which involved applying a magnetic field with a decreasing amplitude tailored to the demagnetization factor of each sample. The findings revealed that this deperming process resulted in a significant reduction of 95% and 92% in the permanent magnetization of the steel plate and the hollow cylinder, respectively. These results highlight the efficacy of the Deperm-ME method within a Drive-in deperming setup. |
