Magnetic ferrofluid playdough, also known as "magnetic putty," is a type of toy or educational tool that consists of a soft, pliable material that is infused with magnetic ferrofluid. Ferrofluid is a liquid that becomes strongly magnetized in the presence of a magnetic field. When placed in the presence of a magnet, the ferrofluid in the playdough becomes concentrated around the magnet, allowing the playdough to be molded and shaped in a variety of ways. Magnetic ferrofluid playdough is often used as a educational tool to demonstrate the principles of magnetism and the properties of ferrofluid. It is also used as a toy and can be molded and shaped in a variety of ways for entertainment.

This magnetic playdough is a great gift and has many novel uses for makers.
