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.

We have a couple of oil tanks at our plant. One of them does not have a lightning arrester installed. My question is it necessary to install an arrestor on every tank or will this particular one be covered by the arrestor installed on the ajdacent tank, Since all the tanks are close to each other. Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
