1.	A rectangular bar magnet of area 20 cm2 has ability to produce a magnetic field of 2.5 T at a point 30 cm away from its mid point on axial line. If it is assumed that dipole is surrounded by a spherical region in space, then net magnetic flux passes through the sphere is(a) 0(b) 0.005 Wb(c) 0.15 Wb(d) 0.05 Wb
Answer» Answer is : (a) 0 Net magnetic flux through a closed surface is always zero.
