The magnets on the refrigeratorthose small objects that we use to hanging photos, notes and memories could be causing more damage than we imagine. Although they are harmless at first glancescientific studies have begun to reveal possible negative effects associated with prolonged exposure to the magnetic fields generated by these objects. From sleep disturbances to concentration problems, the relationship between magnets and our health has become a topic of growing concern.
science says
A recent study has questioned the safety of decorative magnets on refrigerators. Although the magnetic fields they generate are weak, they could interact with the electronic circuits of the most modern household appliancesespecially those with touch screens or smart systems.
While more research is needed to determine the exact extent of this problem, experts recommend caution when using magnets in newer generation refrigerators.
What’s behind those magnets?
Magnetism is the force that makes magnets stick to the refrigerator.
What is magnetism?
Magnetism is a fundamental force in nature that causes certain materials, such as iron, nickel, and cobalt, to attract or repel other materials. This force originates from the movement of electrons within the atoms of these materials. When electrons align in the same direction, they create a magnetic field.
How do refrigerator magnets work?
- The refrigerator: most refrigerators have a back made of a magnetic material, such as steel. This material is composed of small magnets called magnetic domains. Typically, these domains are randomly oriented, making the object non-magnetic.
- The magnet: The magnets we stick on the refrigerator are also composed of magnetic domains, but in this case, most of the domains are aligned in the same direction, creating a strong magnetic field.
- The attraction: When you bring a magnet close to the refrigerator, the magnetic field of the magnet interacts with the magnetic domains of the steel of the refrigerator. This interaction causes the steel’s magnetic domains to align with the magnet’s magnetic field, creating a pull which makes the magnet stick to the refrigerator.
Why are some magnets stronger than others?
The strength of a magnet depends on several factors, such as:
- The material: Magnets made of neodymium are much stronger than ceramic magnets.
- The size: larger ones have more aligned magnetic domains, generating a stronger magnetic field.
- Temperature: The strength of a magnet decreases as the temperature increases.
Magnets on traditional refrigerators
If your refrigerator is a old model, no touch screens nor sophisticated electronic systems, you can decorate your door with all the magnets you want without any problem. These simpler appliances use basic mechanical and electrical mechanisms that are not affected by the magnetic fields generated by magnets.
Unlike modern refrigerators, which incorporate components sensitive electronics such as magnetic sensors and touch screens, traditional refrigerators are much more resistant to external interference. Therefore, you can continue enjoying your decorative magnets without worrying about damaging your appliance.
How to put magnets on the new refrigerator?
If you have a modern refrigerator and you want to continue decorating with magnets, there are alternatives safer. The magnetic boardsavailable in different sizes and designs, allow you to create a space dedicated to your memories.
Another option is to paint a wall with magnetic paintturning it into a versatile surface where you can organize your magnets to your liking. This way, you can enjoy your magnets without putting the operation of your refrigerator at risk and add a personal touch to your home.
Perfect refrigerator care
- Location and leveling: to ensure a optimal performanceplace your refrigerator in a cool and dry placeaway from heat sources. It is essential that it is level to avoid vibrations and ensure proper functioning of the cooling system. You can adjust the legs to level it.
- Regular cleaning: keep your refrigerator clean to avoid proliferation of bacteria and bad odors. Clean the interior at least once a week with a solution of baking soda and warm water. Don’t forget to clean the rubber door seals and condensation coils.
- Maintenance: Perform periodic maintenance to extend the life of your refrigerator. Defrost the freezer regularly if manual, lclean the condensation coils and check the condition of the rubber seals. Adjust the temperature according to the manufacturer’s recommendations.
- Correct use: avoid overloading the refrigerator and Store food properly wrapped. Allow hot foods to cool before adding them. Do not open the door frequently to avoid cold loss.
