In this work we present novel experimental data of the magnetic permeabilization of the mammalian cells in high pulsed magnetic fields up to 16.4 T. Two designs of the multilayer solenoid type pulsed inductors, which were adapted for the biological experiments are presented. The induced electric field is analyzed using the finite element method analysis. The experimental methodology and the pulsed magnetic field setups are overviewed. The experimental results with mouse myeloma cell line Sp2/0 in pulsed magnetic field after pulse bursts and single pulse treatment are presented. The SYTOX ® Green dye was used for the estimation of the permeabilization process efficacy. It has been shown that the 16.4 T sub-millisecond low (< 1.1×10 5 T/s) dB/dt magnetic field pulses do not cause any observable dye uptake changes using the proposed methodology. The short repetitive microsecond range pulses (dB/dt > 0.8×10 6 T/s) result in an average up to 2.6±0.5% increase of the dye uptake.

“…4 is evaluated. It can be seen that an inductor would not be damaged after the pulse when α and β are approximately in the range of (3,5). This means that the applicable inductor windings per layer number n 1 would be in the range of (8, 12) and layer number n 2 would be 2, 4, 6.…”

The optimization of pulsed power inductors' geometry is a difficult multi-dimensional task. On the one hand, an inductor could be destroyed because of the Joule overheating, on the other hand, it might be damaged by the Lorentz forces acting in its windings. The magnetic field pulse up to 50 T is the target while fields of this magnitude are the interest in many scientific applications. All factors mentioned are directly dependent on inductor's geometry, i.e. on the number of winding layers and windings per layer. Therefore, a detailed analysis of thermodynamic, electromagnetic and mechanical processes is inevitable and was carried out for different geometrical inductor configurations to reach the goal: a non-destructive inductor that can meet required magnetic field parameters. Direct calculation methods were used to create universal algorithms in MATLAB environment. The zone of inductor geometries, where stresses do not exceed the yield strength of materials, inductor is not overheated and generated magnetic field magnitude is in acceptable range, is given as a result which enables to manufacture new prototypes saving additional costs and time.
