# Surface Attract

> **Note:** **What is it about?**
>
> This page documents the **Surface Attract modifier** of the particle system in **Cinema 4D**. It pulls particles toward dynamic object surfaces — deflecting or fully capturing them — for effects like iron filings, creeping swarms or magnetic accretion.

This Modifier can be used to simulate forces of attraction between dynamic objects and particles. This allows particles to be deflected in their trajectory or even captured completely. There is no collision detection between the particles and the surfaces. Penetrations can therefore still occur.\
The following video shows an example in which particles are automatically deflected along a surface that lies in their path.
