Acylindrical bar magnet whose mass is 0.07 kg, diameter is 1 cm, length is 3 cm, and whose magnetic dipole moment is 8, 0, 0 a · m2 is suspended on a low-friction pivot in a region where external coils apply a magnetic field of 1.7, 0, 0 t. you rotate the bar magnet slightly in the horizontal plane and release it. (for small angles in radians, assume sin(θ) ≈ θ.) (a) what is the angular frequency of the oscillating magnet? (b) what would be the angular frequency if the applied magnetic field were 3.4, 0, 0 t?
