why and how does ferrofluid create spikes when attracted to a magnet?
In: Physics
Magnetic fields operate on field lines. So, instead of imagining a magnetic field as a sphere, or hourglass shape, imagine it more as something like this: [https://ds055uzetaobb.cloudfront.net/brioche/uploads/MUtOQWcxPp-magneticfieldlines.png?width=1200](https://ds055uzetaobb.cloudfront.net/brioche/uploads/MUtOQWcxPp-magneticfieldlines.png?width=1200)
The spikes are literally the fluid being attracted to the magnetic lines. We just don’t notice this with solid magnets because we can’t see it.
