# Write Off the Magnet explained — Invaders from the Infinite

> Chapter companion for Invaders from the Infinite by John W. Campbell.

## What happens

Arcot and his team engage the Thessian forces in Antarctica, but their magnetic beam fails against shielded Thessian technology. After a devastating battle that destroys the terrestrial squadron, Arcot uses artificial matter to burrow underground and then emerge inside the Thessian dome. He destroys the dome and the Thessian ships with a hyperboloid energy blast, then decides to return to Vermont for time-field installation before heading to Sirius.
