Its official name is an Oxbow. Australian Aboriginals call them Billabongs and that name has stuck with Australians generally.
Magnetic fields flow from north to south in a continuous loop, with the lines of force moving outward from the north pole and curving back towards the south pole. This creates a closed loop pattern that allows the magnetic field to circulate and interact with other magnetic fields.
The drawing shows a version of the loop-the-loop trick designed for small objects.
When a magnetic field is applied to a loop, it induces an electric current in the loop.
To draw the field lines for Earth's magnetic field, imagine the lines coming out of the North Pole and curving back into the South Pole in a loop-like fashion. The lines will be closer together near the poles and spread out as they extend towards the equator. Remember that the field lines form closed loops and do not intersect.
The torque acting on the loop in this scenario is the rotational force that causes the loop to rotate around its axis.
meanders
Billabong or an oxbow. one of those two
A bend in a river shaped like a loop is called an oxbow. Oxbow lakes are formed when a meander is cut off from the main river channel, often due to erosion and sediment deposition.

A billabong is formed when a river winds so much that it forms a loop, which is then cut off from the river, leaving a long and narrow curved section of water. Billabongs are also referred to as Oxbow lakes
An Oxbow lake. It is where a Meander is cut by erosion & the consequent deposition alters the course of the river. The cut off meander forms an Oxbow.
the answer is meander
meand
A river!
yes
