  • This intriguing ferrofluid is a must-have item for any budding scientist.
  • The magnetic liquid can be manipulated by an external magnetic field creating mesmerising effects.
  • Ferrofluid can be precisely positioned and controlled by an external magnetic field.
  • The forces holding the magnetic fluid in place are proportional to the gradient of the external field.
  • The magnetisation value of the fluid and the retention force of a Ferrofluid in a gap can be adjusted by changing either of these parameters.
