A bar magnet of moment of inertia I and dipole moment μ is held in a uniform magnetic field B with its dipole moment making an angle θ (large) with the field. If it is released from rest from this position, the maximum angular speed attained by it is
A) √(4μB/I) sin(θ/2)
B) √(4μB/I) cos(θ/2)
C) √(2μB/I) cos(θ/2)
D) √(2μB/I) tan(θ/2)
