A) \[11\times {{10}^{-4}}T\]
B) \[10\times {{10}^{-4}}T\]
C) \[0.1\times {{10}^{-4}}T\]
D) \[1\times {{10}^{-4}}T\]
Correct Answer: D
Solution :
A magnetic charge (pole) placed in a magnetic field experiences a force \[F=mB\] Here, \[F={{10}^{-4}}N,\,m=1\,Am\] \[\therefore \] \[B=\frac{F}{m}=\frac{{{10}^{-4}}}{1}={{10}^{-4}}T\] Note: The force on positive magnetic charge is along the field and a force on a negative magnetic charge is opposite to the field.
