Curl of field is zero

Electromagnet

F = the force on each charge

+ indicates repulsion

- indicates attraction

k = the electrostatic constant 

q1 = the quantity of charge

measured in coulombs

q2 = 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:

Piezoelectric effect on bone (Fukada & Yasuda 1956)

Coil therapy system

 

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

 

1 Gauss = 1/10.000 Tesla or 1 Tesla = 10.000 Gauss

Magnetic Energy conversion

• PEMF system energy < 1 Gauss=> neglectable effect

• PEMF system energy >30 – 100< Gauss => some effect

• PEMF system to be effective >> 100 Gauss (10 milli-Tesla)

Cylinder Unit Flat surface coils

Flat surface coilCylinder

Field strength formula’s 

B1 = 1 / (a2 + r3) 2/3 B2 = 1 / (a2 + r2) 2/3

 

a = radius of coil r = distance from center of coil B0 = 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)
