viscosity

Temple University physics department chair Rongjia Tao made headlines in 2008 when he developed a simple device that creates an electric field to thin fuel, thereby reducing the size of the droplets injected into the engine and improving fuel efficiency.

Now, Tao and former graduate student Ke Huang are unveiling their latest research that this same principle, when applied to the human body, can help thin blood and reduce one's risk of heart attack--without the side effects of blood thinners such as aspirin.

After testing numerous blood samples at Temple, the physicists were able to use a magnetic field of 1.3 Telsa (roughly equivalent to what is used in an MRI) for just one minute to polarize the red blood cells, which contain iron, thereby causing those cells to link together in short, streamlined chains flowing down the center of blood vessels and reducing friction along the walls.

The result: smoother blood flow. In fact, after just 1 to 12 minutes of exposure to the magnetic field via a 1,000-pound magnet, blood viscosity decreased by 20 to 30 percent for several hours. Eventually, blood viscosity returned to previous levels.… Read more
