Hi there,

For this slime and for all magnetic objects, any magnets made of neodymium are going to effect the magnetic objects the most. The structure of neodymium magnets makes the magnet resist demagnetization, where the magnet loses its pulling ability, and also has unpaired electrons, causing a stronger field which pulls the magnetic objects with a stronger force.

Hope this helps.
