However, scientific studies have not confirmed that the use of static magnets has any effect on pain or illness. Clinical trials suggest that the positive benefits attributed to magnets may actually come from the passage of time, additional cushioning in magnetic insoles or the placebo effect. In...
Increased standing waves due to dielectric effect. More uniform excitation. Comparing phased array and parallel array coils, which of the following is true? Both types of coils offer improved signal-to-noise and increased field-of-view.

(Ti). These magnets were developed in the 1930s and became popular in the 1940s. Temperature has less effect on Alnico magnets than other artificially created magnets. Alnico magnets can be demagnetized more easily, however, so Alnico bar and horseshoe magnets must be stored properly so they ...
Influence of dental magnets on human brain activity: A quantitative EEG analysis. The magnetic field is known to attenuate mental depression, but it is not clear on the effect of dental magnets on human brain activity. Therefore, this st... A Elias,F Raza,A Vaidyanathan,... - Special care...
