I am not an oceanographer but I imagine there are several different processes which occur to make currents (as currents can from at very different spatial scales).
Large scale processes could be:
1) atmospheric circulation (e.g Hadley cell) - caused by temperature gradients.
2) temperature gradient on the oceans.
small scale processes could be:
1) wind
2) salinity gradients
3) changes in ocean topography
I hope someone will expand on my simple, hypothesised, answer.

Does the ocean current affect the animals inside?
no the ocean current is like a wind.
What are the warm and cold ocean currents of the Atlantic Ocean?
Ocean currents describe itself, a warm ocean current is warm water that has a path anything that gets in way of the path will be taken by the current same for cold water also a new tranport for the water to travel to ocean to ocean
