Pulsed Electromagnetic Field Therapy Science, Myth & Therapy © Magnetron Presentation by G K KABRA ’ S PUBLIC CHARITABLE TRUST MAGNETRON

Geomagnetic Field

Body magnets

Atom dispersion in non-magnetized metal

Atom alignment in magnetized material

Magnetic field lines

High Gauss Value

Curl of field is zero

Electromagnet

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 Direction of lines is in the direction of the electric field The density of the lines represent the intensity of the electric field The number of lines of charge entering or leaving the charge is proportional to the magnitude of the charge Field lines leave the positive charge and enter the negative charge Electric field lines never intersect Field lines begin and enter perpendicular to surface of conductor

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!

Curling Fields

Charged particles moving in magnetic field => magnetic force Magnetic force + electric force => Lorenz force Resulting Lorenz force:  electricity  magnetism

Cylinder UnitFlat surface coils

Flat surface coilCylinder

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)
