These experiments illustrate that paramagnetic ions imbibed in rock brine can shorten the relaxation time of the water protons, but can't effect the relaxation time of oil protons.
实验表明，顺磁离子能加快水相的核磁共振弛豫衰减速度，而对油相信号没有影响。

A steady current is needed to maintain the color effect, thus the paramagnetic paint doesn't work when the vehicle is turned off and hence the vehicle switches back to a default white color.
