Problem

A uniform magnetic field of magnitude

0.30\,\text{T}

is perpendicular to a flat rectangular loop of area

100\,\text{cm}^2

. If the loop is rotated so that the angle between the field and the normal to the loop becomes

60^{\circ}

, the magnetic flux through the loop is a)

3.0\times10^{-3}\,\text{Wb}

1.5\times10^{-3}\,\text{Wb}

2.6\times10^{-3}\,\text{Wb}

1.5\times10^{-2}\,\text{Wb}
