It does this by applying current to the electromagnetic clutch just ahead of the rear differential, locking it entirely if necessary.
An alternative approach is to use electromagnetic rather than seismic information.
The two systems contain quartz-like properties and an electromagnetic current.
Now researchers have used a slab of a new kind of material to focus diverging electromagnetic waves into a narrow cone.
The first step was the realization that electromagnetic energy cannot always be treated simply as a wave passing through space.
In fact gravitational interaction is about 10 times weaker than the electromagnetic .
Maxwell believed electromagnetic waves such as light to be vibrations in the ether.
Light is an electromagnetic wave that can carry angular momentum by way of circular polarization.
Water is a good conductor of electricity and could be channeling electromagnetic currents of the Earth.
There could also be waves of electromagnetic energy both shorter and longer than visible light.
