Ferrofluid Magnetic Liquid Experiment

This activity will how how a ferrofluid can be manipulated by a magnetic field inside of a test tube. Students will be able to see how the ferrofluid behaves unlike a normal fluid.

Full Instructions

Materials

• EMG-905, a mineral oil-based ferrofluid with a saturation magnetization of 400 gauss obtained from Ferrofluidics Corporation.
• Strong magnet (cow magnet, bar magnet, or rare earth magnet).
• Long test tube
