Sonic or ultrasonic devices have been touted as repellents for everything from roaches to insects to rodents, specifically rats and mice. … Some are sold specifically to repel rodents. However, there is little data that these devices repel insects or are effective in rodent control. Do electromagnetic pest repellers workRead More →
Thus, the electric energy density of an electromagnetic wave is equal to its magnetic energy density. Hence, the correct answer is option A. What is electromagnetic wave propagation? The changing magnetic field, in turn, induces an electric field so that a series of electrical and magnetic oscillations combine to produceRead More →
Magnet treatment is relatively safe. Some patients may experience dizziness, low energy, palpitation, nausea, and vomiting. Side effects can include a decrease in blood pressure, or local skin areas can become itchy, burning, and painful; however, side effects only happen in a very small percentage of cases. Is magnetic therapyRead More →
An electromagnetic wave is a wave that is capable of transmitting its energy through a vacuum (i.e., empty space). Electromagnetic waves are produced by the vibration of charged particles. Electromagnetic waves that are produced on the sun subsequently travel to Earth through the vacuum of outer space. What can makeRead More →
