3D Vector Magnitude Calculator

The magnitude (or length) of a vector represents the distance from the origin to the point defined by the vector's components.

Properties:

• |v⃗| ≥ 0 (always non-negative)
• |v⃗| = 0 if and only if v⃗ = (0, 0, 0)
• |kv⃗| = |k| × |v⃗| (scalar multiplication)
• |u⃗ + v⃗| ≤ |u⃗| + |v⃗| (triangle inequality)
