1. The problem statement, all variables and given/known data A cylindrical bar magnet whose mass is 0.08 kg, diameter is 1 cm, length is 3 cm, and whose magnetic dipole moment is <5, 0, 0> A · m2 is suspended on a low-friction pivot in a region where external coils apply a magnetic field of <1.4,0,0> 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 <2.8,0,0> T? 2. Relevant equations τ = μ × B τ = μBsinθ ω = qB/m μ = IA 3. The attempt at a solution My first instinct was to find the magnetic torque on the magnet, using the magnet's dipole moment and the applied magnetic field, but that gives zero.
