- #24A square loop of side `` 1 \,m `` and resistance `` 1\, \Omega `` is placed in a magnetic field of `` 0.5\, T `` . If the plane of loop is perpendicular to the direction of magnetic field, the magnetic flux through the loop is :
(A)zero weber
(B) `` 2 `` weber
(C) `` 0.5 `` weber
(D) `` 1 `` weberdigAnsr: CAns : `` B=0.5 T ``
Angle between `` \vec{B}\, \& \,\vec{A} `` is zero
`` \phi = `` B.A. `` \cos 0 ``
`` =0.5 \times(1) \times 1 ``
`` =0.5 \,Wb ``
