Floor raycast range: The distance of the rays casted from each side (or custom point) of the object to scan the angle of ground below the object.

Floor magnet: Works similar to floor detection, but it is for keeping the object on the ground when going downwards a slope at high speeds. This is the distance the object moves to the ground when it's grounded to maintain collision on it to keep it grounded.

Formula:

Object.floormagnetvar = Object.floormagnet

Object.x += Object.floormagnetvar * cos(ToRad(Object.groundangle + 90))

Object.y += Object.floormagnetvar * sin(ToRad(Object.groundangle + 90))

That is also how floor detection works.

Speed-based floor magnet (checkbox): Activating it makes the floor magnet behave differently based on the speed of the object:

If object is not moving, floor magnet value applied will be equal to the 5% of the main floor magnet value.

But if you're moving, the floor magnet value applied will be based on the current speed compared to the max speed, meaning that going 50% max speed will give 50% floor magnet:

Formula:

Object.floormagnetvar = Object.floormagnet * abs(Object.groundspeed/Object.maxspeed)

Object.x += Object.floormagnetvar * cos(ToRad(Object.groundangle + 90))

Object.y += Object.floormagnetvar * sin(ToRad(Object.groundangle + 90))

Minimum angle for ground unattach: The object will unattach from the ground and get to airborne if it's ground angle is equal or higher than this value and if the speed parameters are met.
