while the integrated hang-up hook allows for convenient storage when not in use

This neodymium mounting magnet has an M6 thread with a 7mm hook

interesting and rewarding

Discs with greater height dimensions have more magnetic material than thinner ones

These Ferrite Pot magnets have a steel casing over a ferrite ring magnet with a threaded M5 hole for attachment purposes to non-magnetic surfaces  CAUTION: Do not overtighten attachment screws as this can potentially cause the magnet to become damaged or cracked

Magnetic Liquid Ferrofluid (30mL) + Thumb Pin Magnets 16mm (4pcs) L_50mm while the integrated hang-up hookFerrofluid is a ferrous nano particle liquid that reacts in the presence of a magnetic field. Ferrofluid is used as an excellent demonstration tool for magnetic experiments and recently it is being used in modern art and for other creative purposes. When the fluid is exposed to magnetic field the particles align magnetically with north and south poles and display amazing shapes, once the magnetic field is removed the fluid returns to its random
