Parallel axis theorem
I = I_cm + Md²
Where: I = moment of inertia (kg·m²) / current (A), I_cm = I_cm, M = mass (kg), d = distance / slit separation (m)
Solved example
Given: I_cm = 7, M = 5, d = 10
Find: I (moment of inertia (kg·m²) / current (A))
- Formula: I = I_cm + M·d²
- Substitute the values: I = 10²·5 + 7
- Result: I = 507
Answer: I = 507
