Discussion Overview

The discussion revolves around whether placing magnets on refrigerator doors affects electricity consumption. Participants explore the implications of using different types of magnets, particularly in relation to the refrigerator's door seals and their potential electromagnetic properties.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • Some participants assert that placing magnets on fridge doors has no effect on electricity consumption.
  • Others suggest that only electromagnets would have an impact, implying that standard magnets do not affect energy use.
  • One participant notes that some refrigerators utilize magnetic door seals, indicating that low power magnets should not matter.
  • A participant expresses concern about the potential for increased temperature at the seal area when a strong magnet is placed, questioning if this could lead to higher electrical consumption.
  • Another participant speculates whether high power magnets could induce more current in the electromagnets, potentially leading to increased electrical consumption or even free energy effects.
  • There is mention of testing whether the seals are electromagnets by using a piece of soft iron, but the practicality and necessity of electromagnets in seals are questioned.
  • Some participants share experiences with different types of seals, noting that many use weak permanent magnets instead of electromagnets.

Areas of Agreement / Disagreement

Participants do not reach a consensus on whether magnets affect electricity consumption. Multiple competing views exist regarding the type of magnets used and their potential impact on energy use.

Contextual Notes

There are unresolved assumptions regarding the nature of refrigerator seals and the specific effects of different types of magnets on electrical consumption. The discussion includes varying interpretations of the relationship between magnetism and energy use.

Dear Experts

Could you tell me does putting magnets on fridge doors consume more electricity or no effect?

Thanks.

No effect.

Did you think there might be?
 
Only if the magnets on your fridge are electromagnets.
 
Did you know the some refrigerators have magnetic door seals to close the door tightly? Putting a few low power magnets on door won't matter.
 
Dear Experts

Thanks for your responses.

@vk6kro
My fridge door seems to be using electromagnetic hidden in the door seals.
I recently put a harddisk magnet at the middle part of the edge of the door, just directly on the seal area.

I did not measure the temperature difference but after leaving the magnet there for about 10 minutes, its felt like there was an increase in temperature at the seal area.

So, I was concerned there could be an adverse effect on electrical consumption if I put a really strong magnet there.


@SteamKing
Yes, that is what i was worried about. The way seals seems to have electromagnets in there as the door seal is quite warm to touch normally.
After putting on the magnet i felt that there was a bit of temperature increase.
Nowadays, are'nt all fridge doors using electromagnets?

@GingerLee
Yes, that's what i have been doing. I have several low power standard fridge magnets on the door. Those I am not concerned. So, do you think that high power magnets on electromagnetic door seals would be a problem? If so, in what way ? Thats what I am trying to find out.

I think given the effect of magnetism on electromagnets, more current could be induced?
If so, it sounds like more electrical consumption?
Or is it the other way round, free energy?

haha.
 
You can check if they are electromagnets. Just attach a piece of soft iron to one of them and cut the power to the fridge.
If the iron falls off or is easier to remove, they are electromagnets.

However, there doesn't seem to be any advantage in using electromagnets when rare Earth magnets are cheap and plentiful and use no power.

My fridge uses soft rubber seals with occasional weak permanent magnets in them. This seems to be adequate.
 
Quite a few deep freezers heat the sealing surfaces to prevent buildup of ice. But I´ve never heard of one using electromagnets. As vk6kro said, the magnet in the door seal is strong enough.
I disassembled seal once and found a strip of magnetic material all along the seal.
 
@vk6kro and mainmonides

Thanks so much for your advice.

Sure, will test it out.

Have a nice weekend!
