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: magnetic or diamagnetic forces, in that it causes neither approach
nor recession, consisting not in attraction or repulsion, but in
giving a certain determinate position to the mass under its
influence.' And then he goes on 'very carefully to examine and prove
the conclusion that there was no connection of the force with
attractive or repulsive influences.' With the most refined ingenuity
he shows that, under certain circumstances, the magne-crystallic
force can cause the centre of gravity of a highly magnetic body to
retreat from the poles, and the centre of gravity of a highly
diamagnetic body to approach them. His experiments root his mind
more and more firmly in the conclusion that 'neither attraction nor
