The Attenuation calculation method for the underwater low-frequency magnetic field of finite-length straight wire
نویسندگان
چکیده
Abstract Usually, when solving the magnetic field distribution of a finite-length straight wire in conducting medium, numerical calculation is required. However, this method has some disadvantages, such as complex calculations and not being conducive to engineering implementation. To solve problem, paper studied attenuation for underwater low-frequency then obtained analytical formula spatial distribution. The simulation results show that, within certain distance, good agreement with results. presented convenient practicability.

The Ampère theorem and the Biot–Savart law are well known tools used to calculate magnetic fields created by currents. Their use is not limited to the case of magnetostatics; they can also be used in time-dependent problems. We show in this paper that the highly classical example of a straight wire,generally treated as a simple magnetostatics problem, should be considered in the framework of ti...
