5.

If the cross-sectional area of a magnetic field increases, but the flux remains the same, the flux density

 [A]. increases [B]. decreases [C]. remains the same [D]. doubles

Explanation:

No answer description available for this question.

 Ankita Jain said: (Sat, Feb 12, 2011 12:02:09 PM) If area is increases flux density will be decreases because they are inversely proportional to each other. B=flux/area.

 Raja Gopal said: (Wed, Nov 23, 2011 12:18:25 PM) flux density = flux/area,web/m^2 so flux will decrease

 Parmanand K Patel said: (Wed, Jun 27, 2012 05:21:47 PM) Apart from this, it is well known that density is inversely proportional to area. There fore increase in one will decrease another.
