Answer / michael for a day

A magnetic flux does not automatically induce a current.
In order to induce a current the conductor needs to
experience changing flux linkage. So you need a conductor
and a flux and something that changes. Therefore a static
flux and a moving conductor will do it or an alternating
flux and a static conductor will do it or a flux that
suddenly appears close to a stationary conductor will do
it. Oh yes, the flux and the conductor need to have the
correct orientation too. Read up about Faraday,
electromagnetic induction and the left/right hand rules.
