What is the relationship between distance from the magnet and the strength of its magnetic field

Magnetic force obeys an inverse square law with distance. The equation for magnetic force is similar to Coulomb's Law (if you are familiar with it). But the key point is that the force is inversely proportional to the distance squared

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
