Therapeutic Core

The zone of the magnetic field where strength is above 35% of the peak value. This is the region of highest therapeutic relevance, where the field is strong enough to deliver meaningful energy to tissue. The Therapeutic Core Flux metric quantifies the total magnetic flux within this zone, and the Concentration Score reports what share of the measured field intensity falls inside it. The threshold was 50% of peak before August 2026; it was lowered to 35% because 50% proved too strict a definition of a strong field, so core flux and concentration figures published before that date read lower than figures published after it for the same accessory.
