High-Density Magnets Created

Judebert writes: "University of California, Riverside scientists have created diradical magnets: magnetic particles that have two unbonded electrons instead of just one. The problem with diradical substances is that they have always been extremely chemically active, so they never stayed around longer than a few microseconds at room temperature. The new substance is stable at room temperature, even when it's in solution. And it's not even metallic. This paves the way for newer, higher-density magnetic and magneto-optical media and devices. You can help distribute the load if you visit the text mirror instead."

Re:Better Magnets == Better Cars

The force (or power) an electric motor can generate is directly proportional to the current going through the motor and the strength of the magnetic field. If the magnetic field is stronger, you can have a motor of the same size but with more power. Or you could have a motor of the same size and power, but it would consume less current. This would give you a longer battery life.

For cars, you could now have more powerful electric motors that consume the same amount of power as current electric motors. Or you could have electric motors with the same power output of todays models but with a lower power consumption.

Stronger magnets make for more effecient electric motors. You can use that efficiency for greater power or greater battery life.
