All throughout the articles on EMF Academy I strongly recommend getting an EMF meter, and for good reason. EMF meter’s allow you to understand amount of radiation around you, and help you to make positive changes to resolve it. Although you can now get really affordable EMF meters like the Meterk (read my review), today I want to show you how you can make a DIY EMF detector for under $12.00!
How To Make A DIY EMF Meter (Detector)
Ok, so I got this idea from a great youtube video that i’ll have at the bottom of the article, but I want to walk you through how to do this, and why it can actually be really useful.
To start with, we just need a basic compass. I picked up this one from Amazon for this.
Now to start with, the reason I italicized “detector” up above, is that what we’re making is not an EMF meter in the traditional sense. I does not give a reading of how much EMF radiation is being detected, or what kind. This DIY EMF detector simply makes us aware of the presence of an electromagnetic field. Also, although radio frequencies can be damaging, using a compass to measure EMFs will only detect electric and magnetic fields.
You will however be able to determine that there are EMFs near, and which direction they are coming from, which can still be helpful as you are moving around your home and trying to find out where there is strong EMF radiation.
Ok, first let’s go ahead and set our compass down on a flat surface, preferably away from any strong EMF fields. Spin it around until the needle is lined up with north to start with. Remember that with a compass like this, it really needs to be flat to give an accurate reading.
To demonstrate how this works, take something like a handheld radio, or cell phone, and slowly move it around the compass. You’ll notice as you move it around the compass that the needle will point away from the field, remember this when you’re doing tests, as it can be tempting to assume that the needle will point to the field.
Now, when you’re using the compass to locate EMFs, whether its tracking the paranormal (for this i’d check out this post) or for locating dangerous amounts of EMF radiation in your home, you first need to be sure that you note in which direction north is. To do this, start by holding the compass flat in your palm in front of you, away from any electromagnetic disturbances. Spin the compass so it is lined up with north, and note in which direction that is by looking up and picking an object in the distance to roughly guide you.
Now, with your palm flat in front of you so the needle can freely move, start walking where you believe there to be EMF radiation or disturbances. If the needle begins to move, move in the direction opposite of the arrow to confirm the presence of the EMFs and to discover there location.
This is great if you can’t afford a quality EMF meter like the Trifield, but still want to confirm the location of EMF radiation. It is also great for testing out the capabilities of shielding materials, and to ensure that the steps you are taking to eliminate EMFs are working.
Here is a video demonstrating this, and where I got the idea!
DIY Gauss Meter
It is also possible to build a much higher functioning Guass Meter (An EMF meter that measures magnetic fields) using parts you can get from your local electronics store.
I’m not going to detail how to do this in this article, because coolmagnetman already wrote up an enormous guide on the details of how to do this (it’s also fairly complicated!). You can check out his instructions for building a DIY gauss meter here.
What To Get If You Don’t Want To Make a Do It Yourself EMF Meter
If you are serious about wanting to reduce dangerous EMF radiation from your life, from your home, and from your office, the first thing you should consider getting is a quality EMF meter. I always recommend the TriField TF2 (read my review) if you can afford it, as it’s simple to use, lasts forever, is extremely accurate, and measures all three types of EMF radiation (electric, radio, and magnetic). If you’re looking for a low cost digital meter the Meterk (read my review) is a new addition to the market, and I absolutely love it for the price.
