Algophobia problems and experience the results before anything actually happens to them. People suffering from this probably have hyperalgesia. The Fear of Pain Questionnaire (currently the FPQ-III) has been used to test for Algophobia in the past and was found to have good internal consistency and test-retest reliability. Algophobia Algophobia is a phobia of pain - an abnormal and persistent fear of pain that is far more powerful than that of a normal person. Algophobia is much more common in elderly people. It can be treated with behavioral therapy and anti-anxiety medication. The term comes from the , "álgos", "pain" and
Persistent current is also true: any persistent electric current is divergence-free, and can therefore be represented instead by a magnetization. Therefore, in the macroscopic Maxwell's equations, it is purely a choice of mathematical convenience, whether to represent persistent currents as magnetization or vice versa. In the microscopic formulation of Maxwell's equations, however, formula_1 does not appear and so any magnetizations must be instead represented by bound currents. In superconductors, charge can flow without any resistance. It is possible to make pieces of superconductor with a large built-in persistent current, either by creating the superconducting state (cooling the material) while charge is flowing
