We know flux density is directly proportional to current.

When current is high flux density is high.

We know that the current directly proportional to flux density (B).

Here the current passing through the conductor is directly proportional to flux density.

We know:

1) pi = NI/S.
2) B = pi/A.

From above relations we can say that as I increases pi increases therefore B of coil increases respectively.

When the current flowing through more large the flux is also increased and it increase. The flux density.

Because high voltage induced flux is more.

As we know that Flux density B = Q/N.

Q - Flux.
N - No. on turns.

As current increases, flux increases then obviously flux density increases because flux is directly proportional to flux density.

As current increases means flux increases by formula pi=n*i.
