Cyclic compression of magnetized plasma irreversibly pumps energy into particles, producing universal power-law spectra predicted by entropy maximization.

Magnetic pumping turns plasma pulsations into a natural accelerator. Each compression cycle, like a blacksmith's bellows strike, hammers a portion of energy into the particles. In 5–10 cycles, electrons accelerate to near-light speeds. This mechanism explains particle streams from Earth's magnetosphere to galaxy clusters. It seems the Universe uses a simple rhythm to create the fastest objects in nature.

🎯 With each cycle of compression and expansion, the internal energy of the plasma grew by exactly 29% — regardless of the already accumulated energy. It's like the magic of compound interest: the system works as an ideal investment fund, with new "contributions" arriving strictly on schedule.

\frac{dN}{dp} = C p^2 \left(1 + \frac{\epsilon(p)}{\epsilon_b}\right)^{-\alpha-2}

The larger α, the steeper the drop in particle number with increasing energy ε(p). The characteristic energy ε_b separates the thermal core from the nonthermal tail, like a threshold between a calm backwater and a mountain stream.

p_H = \frac{e \langle B \rangle \lambda}{c}

A particle stops accelerating when its gyroradius equals the size λ of the accelerator. It's the moment when it can no longer make the magnetic turn and flies out, like a motorcyclist leaving the race track.
