The excerpt represents the core issue or deciding factor on which you must meditate, and is drawn from Faraday as a Discoverer by John Tyndall: influence. When the magnetic force was developed, the bulbs
remained in their first position, even when one was filled with
nitrogen, and the other as far as possible exhausted. Nitrogen,
in fact, acted 'like space itself'; it was neither magnetic nor
diamagnetic.
He cannot conveniently compare the paramagnetic force of oxygen with
iron, in consequence of the exceeding magnetic intensity of the
latter substance; but he does compare it with the sulphate of iron,
and finds that, bulk for bulk, oxygen is equally magnetic with a
solution of this substance in water 'containing seventeen times the
weight of the oxygen in crystallized proto-sulphate of iron, or 3.4
