3.

For a given wirewound core, an increase in current through the coil

 [A]. reverses the flux lines [B]. decreases the flux density [C]. increases the flux density [D]. causes no change in flux density

Explanation:

No answer description available for this question.

 Praveen said: (Sep 23, 2011) As current increases means flux increases by formula pi=n*i.

 Sunitha said: (Nov 11, 2013) 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.

 Brahma Krishna said: (Feb 14, 2015) Because high voltage induced flux is more.

 Roshik said: (Mar 4, 2015) When the current flowing through more large the flux is also increased and it increase. The flux density.

 Venkatesh said: (Dec 13, 2015) 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.

 Stark said: (May 2, 2016) Here the current passing through the conductor is directly proportional to flux density.

 Parimal Bera said: (Mar 24, 2017) We know that the current directly proportional to flux density (B).

 Amardeep said: (Apr 12, 2020) We know flux density is directly proportional to current. When current is high flux density is high.
