A field is an enclosed area of land used for
farming. Traditionally fields were measured
in acres, the current unit of measurement is
the hectare (2.47acres). In the Middle Ages,
the farmland of an English rural community
was often divided into three large fields
(the open-field system). These were worked on
a simple rotation basis of one year wheat,
one year barley, and one year fallow. The
fields were divided into individually owned
strips of the width that one plough team with
oxen could plough, about 20m (66 ft). At the
end of each strip would be a turning space,
either a road or a headland.
A field in physics, is a region of space in
which an object exerts a force on another
separate object because of certain properties
they both possess. Other fields of force
include electric fields (caused by electric
charges) and magnetic fields (caused by
magnetic poles), either of which can involve
attractive or repulsive forces.
