Builders of the pyramids were well acquainted with magnetic forces and used it in the preservation of mummies from natural decay. Cleopatra wore a small magnet on her forehead to preserve her beauty. Paracelsus a Swiss alchemist and physician, who lived in the 15th century, pioneered working with magnets. Michael Faraday, who lived in the 18th century, laid the foundation for Biomagnetics and magneto-chemistry and established all matter is magnetic in one way or other. Franz Mesmer, a healer in the 18th century used magnets to cure his patients. Louis Pasteur, who lived in the 19th century, discovered the geo-magnetic field had a positive effect on the growth of plants. Our body’s natural magnetic field is created by the flow of electrically charged ions in and out of cells, and the transmission of electric impulses through cell membranes. Only Pulsed electromagnetic force can influence on a cellular level.
F = the force on each charge + indicates repulsion - indicates attraction k = the electrostatic constant q 1 = the quantity of charge measured in coulombs q 2 = the quantity of charge measured in coulombs r = the radius of separation from the center of one charge to the center of the other charge Coulomb's Law - The law of force
Properties of field lines <ul><li>Direction of lines is in the direction of the electric field </li></ul><ul><li>The density of the lines represent the intensity of the electric field </li></ul><ul><li>The number of lines of charge entering or leaving the charge is proportional to the magnitude of the charge </li></ul><ul><li>Field lines leave the positive charge and enter the negative charge </li></ul><ul><li>Electric field lines never intersect </li></ul><ul><li>Field lines begin and enter perpendicular to surface of conductor </li></ul>
The difference between electric and magnetic field lines => Electric field exerts forces on electric charges => Magnetic field exerts forces on magnetic poles
=> An electric field exerts no force on a stationary magnetic pole => A static magnet can not generate an electrical induction !
1 Gauss = 1/10.000 Tesla or 1 Tesla = 10.000 Gauss Magnetic Energy conversion 1 Gauss 0.0001 Tesla 0.1 milli Tesla 50 Gauss 0.005 Tesla 5 milli Tesla 100 Gauss 0.01 Tesla 10 milli Tesla
<ul><li>PEMF system energy < 1 Gauss => neglectable effect </li></ul><ul><li>PEMF system energy >30 – 100< Gauss => some effect </li></ul><ul><li>PEMF system to be effective >> 100 Gauss (10 milli-Tesla) </li></ul>
Field strength formula’s B 1 = 1 / (a 2 + r 3 ) 2/3 B 2 = 1 / (a 2 + r 2 ) 2/3 a = radius of coil r = distance from center of coil B 0 = strength of field in center of coil B = strength of field at distance r from coil
EMF voltage V = n x a x dB/dt V = Voltage n = number of turns of the electromagnetic coil a = area of the loop dB/dt = Signal rise-time (speed of induction)
