How many PEMF coils are there in Ereada® mats? What is the intensity and frequency?
Ereada® PEMF is more potent than that of other mats.
Old mats had only one 50-60 Hz frequency setting. Newer mat controllers offer a choice of PEMF frequencies. They function in the Ultra Very Low-Frequency range of magnetic pulsations between 8 and 64 Hz.
There are nine pulsed magnetism settings in the new purple Ereada amethyst mats and controllers since 2019. You can select any of these nine settings by pressing the PEMF button repeatedly. The controller's screen will show for a moment the set PEMF level (1-9), then will switch to the temperature level set before (1-7).
Level 1 is 8 pulsations per second (8Hz), which is the first harmonic Schumann resonance.
Level 2 is 16 pulsations per second (16 Hz)
Level 3 is 24 pulsations per second (24 Hz)
Level 4 is 32 pulsations per second (32 Hz)
Level 5 is 40 pulsations per second (40 Hz)
Level 6 is 48 pulsations per second (48 Hz)
Level 7 is 56 pulsations per second (56 Hz)
Level 8 is 64 pulsations per second (64 Hz)
Level 9 is the random program auto-changing frequencies between 8 and 64 Hz every 1-2 seconds.
The PEMF program cycles 20 minutes ON and 100 minutes OFF.
It repeats four cycles if you set the timer for 8 hours or more extended sessions.
The gauss output for the PEMF is 100 to 400 Gauss depending on the frequency (higher frequency -> higher gauss). Static magnets have 300 gauss output if measured directly on the magnet or coil.
There were three PEMF Coils in the upper body part of the mat on the older model lines of Ereada® Purple and mixed Gemstones mats bigger than mini size.
In the second half of 2019, the model lines of Gray and Purple mats will have the following number of PEMF coils:
Mini mat 20"x32" - Two Coils
Midsize mat 24"x59" - Three Coils
Professional mat 29"x73" - Four Coils
Single size mat 35"x75" - Five Coils
Purple and Gemstone mats also have twelve static (permanent) magnets in the lower body part. Purple and Gemstone mini mats permanent magnets are distributed throughout the mat.
Magnetic Field disappears with distance as per the reverse square law. The intensity goes down in direct proportion to the square of the distance from the coils.
So more powerful PEMF produces a better overall effect. The higher number of magnetism coils do a better job generating a more uniform field above the mat surface.
