Current
* Some current is created by storms
  - produced by muscles
* affects fields
  - magnetic fields
* also flow in the sun.
* always flows from the anode to the cathode.
* are extremely variable, from nothing to a fast, steady flow of three knots or more
  - found in rivers, ponds, marshes and even swimming pools
  - large moving rivers of water in the ocean
  - mostly wind driven, but with low velocity reducing with depth
  - normally strong during the full moon
  - of different density and proportions
  - often unpredictable, moving rapidly and quickly changing direction
  - particularly hazardous in winter
  - sometimes strong both on the surface and at depth
  - streams of water running through a larger body of water
  - stronger on spring tides
  - strongest during large ebbs
* are the avenues of movement
  - highways of the ocean
  - variable in time and space
* associated with large internal waves in the ocean can modify the surface wave field.
* become very swift and swirly, eddies disappear, and swims are very long.
* bring in hammerheads, grey reef sharks and mantas.
* can be incredibly strong, both horizontally and, even more dangerously, downwards.
* can be strong and change as divers circle the pinnacle
  - drown even the best swimmer
  - very strong sometimes
  - change quickly
  - either be warm or cold
  - flow through one or more clouds and the earth
* carries particles.
* carry fish, as well as their eggs and larvae
  - scent great distances, enabling game fish to accurately home on their source of food
  - the sand to the bottom of the ocean and later bring it up under the beach
* change direction, which in turn affects everything from rainfall to surface temperatures.
* converge and upwell at specific sites, bringing food and oxygen together.
* created by motions in the Earth s core generate the Earth s magnetic field.
* creates fields
* develops over time.
* dissipates energy
  - kinetic energy
* drives mill wheels
* exist as surface currents and vertical currents.
* flow across the large bodies of water from continent to continent
  - like rivers, waves crash against seashores and tides rise and fall
* flowing in the ocean contribute to GICs by entering along coastlines.
* follows routes
  - the path of least resistance to the ground
* generates electricity.
* go in one direction at a time, and can be given a very strong charge or a very weak charge.
* has load.
* increases danger.
* involve time in transmitting signals.
* is an electrical phenomenon
  - caused by convection
* is created by heat
* is generated by cilia
  - forces
  - located in water
  - through a point in a circuit
* move bodies of water from one location to another, like a river flowing within the ocean
  - large amounts of water great distances
  - laterally, loose heat and cool, then sink
  - sand and sediment in and out of estuaries and can erode away shorelines
  - warm water to cooler regions and cold water into warm latitudes
* moves water.
* occur in all materials, but the amount of current depends on the nature of the material.
* often travel along electric field line directions and generate magnetic fields.
* passes through materials.
* preferentially travel along lines of least resistance.
* produces current
  - output current
* provide flushing and a source of oxygen to the organisms living on the reef.
* removes waste.
* requires drive voltage
* reveal themselves by the shape of the waves.
* similarly run into resistance from atoms as they flow through wires.
* swirling around the normal cores generate magnetic fields parallel to the applied field.
* tend to be strong.
* then carry the sun s energy to the surface in the convective layer.
* transfers heat energy
  - thermal energy
* transports energy.
+ Ampère's circuital law, Note on free current versus bound current: Laws of physics
  * All current is fundamentally the same, microscopically. There are often practical reasons for wanting to treat bound current differently from free current. For example, the bound current usually originates over atomic dimensions, and one may wish to take advantage of a simpler theory intended for larger dimensions.
