In November 2009: The commercial flight time is listed at 3 hours and 40 minutes.
The electrical field force acts between two charges, in the same way that the gravitational field force acts between two masses.
magnetic field
An electric force is the force on an electric charge or an electrically charged object when immersed in an electric field.
tamera
Andrews AFB is an Air Force installation, not a person.
Andrews air force base
An Air Force Base has a flight line or flying mission.An Air Force Station does not have a flight line, or a flying mission.An Air Base (without the "Force") is on foreign soil or foreign owned or a shared Base.
Gravitational force field, electric force field, magnetic force field.
Pole strength is ability of poles to produce lines of force where is field strength is force which a magnetic poles experiences when places in magnetic field.
field force
This is the Electromagnetic force. (Technically, it's the Lorentz force, which is the force on a charge due to an electromagnetic field, but either will do.)
