Thanks for everyone who can help me and who have a time for this.
Magnitude means the length of a vector (distance between two points). It's used in ROBLOX to find the distance between two positions, using the formula "sqrt(x2 + y2 + z2)" according to the wiki. People use > to see if the distance is at a certain point to do a certain thing such as alert a player. You can learn more in depth about this here.
Example
local position1 = workspace.Part1.Position local position2 = workspace.Part2.Position local distance = (position2 - position1).Magnitude -- find distance between two parts if distance > 5 then -- do stuff... end
