Isocontours of the <strong>magnetic</strong> <strong>field</strong><br />
strength for a non-rotating M = 1.4 M ⊙<br />
model <strong>with</strong> a circumferential radius of<br />
R = 12km in the non-<strong>magnetic</strong> case. The<br />
peak value is B p = 5.34 × 10 17 G which is<br />
the maximum possible. Upper physical<br />
limit for B p due to buoyancy estimated<br />

where f ≃ 0.01. Resulting maximum<br />
<strong>field</strong> strengths of B = 10 16 − 10 17 G.<br />
