If you import your Cinema 4D characters as .objs.  The magnet can modify portions of each character.

However, you must be familiar with what each portion of a magnet does (there are three)

The magnet base (small rectangular object), the magnet (horseshoe), and the mag zone (the circle.

The rules: when the horseshoe is in contact with the base, nothing happens, when you move it away from the base, it drags a portion of the object with it.

The mag zone determines how much of the object is moved.  For example, if you make the circle small, a small portion of the object moves, if you make it larger more of the object moves.

If you move the circle notice the effect it has on the object (the further you move the circle away from the object , the less effect it has and vice versa.
