relatively weak flow to pass repeatedly through the operational zone. This
is usually the case when the strong flow is difficult to create or cannot be
fully used in one pass and the effect may be cumulative."@en

repeatedly through an operational zone."@en
→ skos:example → "Coil of an electromagnet.<br/> The required magnetic field
strength can, in principle, be obtained with just a single coil. However, in
order to do this, an enormous current would have to be passed through the
coil. Instead, a relatively weak current is used which is passed through the
coil many times, combining the magnetic fields of each coil to make a single
strong field."@en
