We often use various forms of magnets in our daily lives, and many people have definitely never seen magnetic liquids.
Magnetic fluid is a magical liquid. Simply put, it is a fluid-like magnetic substance. It is covered with spikes and can follow the magnetism at will. Change shape, like magic.
Magnetic fluid is a colloidal liquid mixed with magnetic solid particles, carrier fluid and surface active agent. It is non-magnetic when static. Attraction, magnetism occurs only when there is an external magnetic field.
When the magnet is close, the magnetic fluid will disperse along the direction of the invisible magnetic induction lines, showing a peak shape. It looks a bit like the tip of a durian and looks a bit creepy.
If placed in Glass bottle becomes very interesting. The shape of the magnetic fluid will continue to change with the change of the horizontal magnetic field or the vertical magnetic field. Change is like a follower, no matter where the magnet turns, it always follows closely.
For a while, they gathered into a small mountain peak, and for a while, they scattered into countless small black balls. The ever-changing changes are quite interesting.
If you bring a lit match close to it, it will slowly disperse.
The top tips will branch out smaller and smaller, becoming denser and denser, and will turn into a pile when they are best burned. Dregs. Although the original liquid state of the magnetic fluid is lost, the magnetism still exists.
