1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

Thermomagnetic generators (TMGs) represent a promising solid-state technology for low-grade waste heat recovery. While extensive research has addressed working materials and heat transfer optimization, systematic analysis of magnetic field source design in TMGs remains underexplored. This study presents a parametric finite element analysis of the magnetic field source in a TMG. Magnetostatic and transient simulations were performed to evaluate the effects of permanent magnet (PM) material (neodymium-iron-boron [NdFeB], Alnico, and Ferrite), its dimensions, and air gap width, on the TMG output power and specific power. It is shown that reducing PM thickness yields a substantial gain in specific power output per PM mass, while an increased air gap can be maintained without significant effects on output power. The study also investigates Alnico PM as a sustainable, rare-earth-free alternative. These findings contribute to the development of mass-optimized and cost-effective thermomagnetic energy harvesters.
