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: and Seebeck had indicated the existence of a repulsive force

vegetable and animal tissues, and found them all amenable to
magnetic influence. No known solid or liquid proved insensible to
the magnetic power when developed in sufficient strength. All the
