According to Sabino Metta, a behavioral psychologist, the phobic reaction is a learned behavior. A common example of this would be an elderly person who hears about all of their friends suffering from various ailments and pains. This person will begin to anticipate the
Persistent current Persistent current Persistent current is a perpetual electric current, not requiring an external power source. In electromagnetism, all magnetizations can be seen as microscopic persistent currents. By definition a magnetization formula_1 can be replaced by its corresponding microscopic form, which is an electric current density: This current is a bound current, not having any charge accumulation associated with it since it is divergenceless. What this means is that any permanently magnetized object, for example a piece of lodestone, can be considered to have persistent electric currents running throughout it (the persistent currents are generally concentrated near the surface). The converse
