Here's proof bedroom clocks can give strong magnetic/electric fields

I didn’t believe this at first… then I checked for myself yesterday:

I used two meters: UHS2 from AlphaLab, and the Cornet ED88TPlus.

Lloyd already said that in this video:

Still I had no idea how strong the magnetic/electric fields were until I measured both.

Currently I use a battery-operated clock, and for alarm I prefer my iPAD.

However the latter has wi-fi, bluetooth and cellular data (all 3) turned off, no one should put any phone or device near the bed since it can also emit high EMFs.

Here’s the recording:


Measured in this video (recorded in October 20, 2018):

– The iCraig Alarm Clock Stereo Radio (model: CMA3004)

– A battery-operated talking alarm clock (from Jixia), that uses 2 “AA” batteries. Download the manual here (in portuguese only):

– The iCraig one is connected directly to a power outlet. It also allows for 2 “AAA” batteries to be inserted (what I didn’t do, as you can see from this recording), only useful for a scenario of a power outage.

– In the beginning of this video the Cornet ED88TPlus meter is showed registering 0.55 mG (or 0.1) for my bedroom, in terms of magnetic field. Note the iCraig alarm clock isn’t connected to a power outlet YET.

At 0:45 I move the Cornet meter closer to the Jiaxi clock. We see an increase in the magnetic field, however these are caused by the other bedroom, where there’s a wi-fi router (VR900) and a few other devices (that not only give RF radiation but increase the surrounding magnetic field, too).

I’ll confirm that after 02:37 , when the Jiaxi battery-operated clock is placed above the table, and there’s no increase at all.

– During this recording I also measure the electric field when close to the iCraig alarm clock. Although this type of EMF (just like magnetic field) isn’t measured with precision by the Cornet meter, nonetheless remember it says from a close distance 9-11 V/m.

– 04:08 – The gaussmeter (UHS2) registers 0.1 mG for this bedroom.

– At 07:06 the iCraig alarm clock is turned on, so it’s connected to a power outlet now. At 07:40 and after 15:38 , with help from the UHS2, watch how even from a considerable distance there’s a strong magnetic field. After 10:50 the Cornet “says” the same thing.

– 12:58 – With the Cornet I measure the electric field again, and the numbers are also higher.

– 17:39 – The iCraig device is now near the bed, in a location where most people would use it. Watch the following minutes and pay attention after 25:24 , when I turn off the iCraig from the power outlet: a massive decrease in the registered levels.

– 26:40 – In here I show more about the battery-operated alarm clock from Jiaxi. Once again you’ll see this clock doesn’t influence these EMF meters.

P.S. Found another review from Lloyd showing the same thing:
