A uniform megnetic field, parallel to the plane of the paper exixted in space intially directed from left to right. When a bar of soft iron is placed in the field parallel to it, the lines of force passing through it will be represented by



A

B

C

D

Text Solution

Verified by Experts

The correct Answer is:
B

(b) Because of large permeability of soft iron, magnetic lines of force prefer to pass through it. Concentration of line in soft iron bar increase as shown in Fig. (b)
