These things do work!They effectively cover the outlet box, provide a nice interface with the drywall.
Electrically, there would be some added common mode inductance (over plastic) having the wires go through a window in a steel plate.
In the GHz range, this might provide a few dB of added rejection so far as radio frequencies going into your wall outlet (which thankfully isn’t a problem anyway).Subjectively, these outlet covers, magic wood blocks, magic power cables and so on work the same way as many other discretionary “consumer†products like the gas line magnetizer.
Chemists say they can’t work, as the magnetic field has no impact at all on the energy release etc. There is no way they could be convinced it works as advertised.
Users say that they kept track after installing them and got XX% better gas mileage, there is no way they could be convinced it doesn’t work.
Who is right?
Both sort of.
The Chemist is right, the magnetism has NO impact on the gasoline or combustion at all.
The drivers are right, they really did get better gas mileage.How / Why?
A simple, well-known psychological principal marketing depends on is at work.
The drivers had an expectation that the magnetizer would help, they invested time and money buying /installing it affirming that expectation.
Subconsciously, they drive more conservatively as they expect better gas mileage and as a result, got better gas mileage..
What you want and expect genuinely shapes your expectations and actions even if subconsciously. This is why one does blind testing “when you really have to knowâ€, you need to remove those expectations leaving only your hearing sense.Spend money of a fancy outlet cover, fancy cables, fancy doodads and you’re also in the world of discretionary “consumer†products like the gas line magnetizer.
Unlike the magnetizer, there isn’t a way to even keep track of mileage, just how it sounds to you after the change it.
Like the magnetizer, you couldn’t convince the users that there might be a less obvious, more technical explanation for what appears obvious to them.Tom
