A 10 A electrodynamic ammeter is controlled by a spring having a constant of 0.1 × 10-6 Nm/degree. The full-scale deflection is 110°. Determine the mutual inductance of the instrument when measuring a current of 10 A. The mutual inductance of 0° deflection is 2 μH and the change in mutual inductance is linear with deflection is _____( in μH, up to 2 decimals)
