The strength of a magnetic pole is measu...

The strength of a magnetic pole is measured in terms of pole strength. Pole strength depends on number of free poles exposed at the end of the magnet. Number of free poles exposed at the end of magnet inturn depends on the area of cross section of the magnet. A bar magnet has a pole strength 'K'. If is cut into 2007 parts as shown in the figure. The pole strength of each piece now is ____

A

2007K

B

`(K)/(2007)`

C

K

D

`K+2007`
