WBJEE PYQs for Magnetism And Matter with Solutions

1.
At two different places the angles of dip are respectively $30^{\circ}$ and $45^{\circ}$. At these two places the ratio of horizontal component of earth?s magnetic field is
- $\sqrt{3}:\sqrt{2}$
- $1:\sqrt{2}$
- $1:2$
- $1:\sqrt{3}$

2.
A bar magnet has a magnetic moment of $200\, A \,m^2$. The magnet is suspended in a magnetic field of $0.30\, N\, A^{-1}\, m^{-1}$. The torque required to rotate the magnet from its equilibrium position through an angle of $30^{\circ}$, will be
- $30 \,N\,m$
- $30 \sqrt{3} \,N \,m$
- $60\, N\, m$
- $60 \sqrt{3} \,N \,m$
