Ever wondered if your soda can has magnetic properties?

Despite common knowledge that aluminum isn’t typically attracted to a magnet, you might be surprised to find out that under certain conditions, it can slightly interact with one.

This blog post delves into the fascinating science behind magnetism and aluminum cans, addressing whether or not your Coke or Pepsi container holds hidden magnetic prowess. Get ready — we’re about to pop open some intriguing facts!

Can a Soda Can Be Magnetic?

Exploring the concept of magnetism and its effects on materials

Magnetism is a fascinating force, ever-present yet invisible. Like gravity, it provides us hints about the unseen world of physics.

It’s this force that allows magnets to attract objects made from iron or steel, such as nails and paper clips, with an intriguing pull.

However, not all materials yield to its allure – aluminum soda cans and copper pennies for instance don’t feel the magnetic attraction.

Taking a deeper dive into understanding magnetism requires exploring its interactions with different kinds of materials. The key player here is their atomic structure which quite literally makes them ‘stick’ (or doesn’t) in response to magnets.

Intriguingly enough though there are exceptions like aluminum which can become slightly magnetic under the influence of strong magnetic fields despite our everyday experience suggesting otherwise!

Understanding the properties of aluminum and its interaction with magnets

Aluminum is a widely used material, known for its lightness and versatility. When it comes to magnets, aluminum typically does not have any magnetic properties.

While some metals like iron and steel are attracted to magnets, aluminum resists the pull.

This means that if you try to stick a magnet on an aluminum soda can, it won’t stay put.

So why doesn’t aluminum have magnetic attraction? Well, it all has to do with its atomic structure. Unlike metals such as iron or nickel, which have unpaired electrons that align with magnetic fields, aluminum has paired electrons that cancel out this effect.

As a result, in everyday scenarios, you won’t see a soda can magically sticking to your fridge or attracting metal objects around it.

It’s important to note that under extremely strong magnetic fields, such as those generated by powerful electromagnets or in specialized laboratory settings, aluminum can exhibit very weak magnetism called paramagnetism.

Factors Affecting Magnetism in Soda Cans

Thickness and composition of the can

The thickness and composition of a soda can play a significant role in its magnetism. While aluminum is generally not magnetic, the thickness of the can may affect its interaction with magnets.

In strong magnetic fields, aluminum cans can become slightly magnetic due to induced magnetism. However, in everyday experience, aluminum does not exhibit magnetism. It’s important to note that other materials such as plastic, wood, and tin cans are also non-magnetic.

So if you’re trying to test the magnetism of a soda can, remember that it’s primarily made of non-magnetic materials like aluminum which won’t be attracted to magnets like iron or steel would be.

Presence of any magnetic coatings or materials

The magnetism of a soda can can also be influenced by the presence of any magnetic coatings or materials. While aluminum itself is not magnetic, it is possible for soda cans to have a thin coating or layer that contains magnetic materials.

These might include paint with iron particles, adhesive strips with embedded magnets, or even stickers made from ferromagnetic materials. However, it’s important to note that these cases are not common in everyday soda cans and are usually specific to certain purposes like promotional items or novelty cans.

So if you’re wondering whether your average soda can sticks to a magnet, the answer will likely be no.

Conducting Magnetic Experiments with Soda Cans

Testing the magnetism of a soda can

To determine if a soda can is magnetic, you can conduct a simple experiment using various magnets. Here’s how you can test the magnetism of a soda can:

  1. Gather your materials: You will need different magnets, such as a refrigerator magnet, a neodymium magnet, and an electromagnet if available.
  2. Start with a clean soda can: Ensure that the soda can is empty and free from any liquid or residue.
  3. Place the refrigerator magnet on the outside of the soda can: Hold the refrigerator magnet against the outer surface of the soda can and observe if it sticks. Remember that aluminum is not typically attracted to magnets, so it is unlikely that the refrigerator magnet will stick to the can.
  4. Try stronger magnets: Repeat step 3 using stronger magnets like neodymium magnets. These magnets are much more powerful than a refrigerator magnet and might exhibit some attraction to certain parts of the aluminum surface due to slight magnetic properties that aluminum may acquire in strong magnetic fields.
  5. Use an electromagnet (if available): If you have access to an electromagnet, power it up and hold it close to the soda can without touching it directly. This will create a strong electromagnetic field which could potentially induce mild magnetic properties in the aluminum material but don’t expect anything significant.
  6. Observe and document your findings: Record whether each magnet sticks or shows any signs of attraction to the soda can. This will help you analyze and compare their effects on aluminum.

Demonstrating the effects of different magnets on the can

When experimenting with different magnets and soda cans, you can observe various intriguing effects. Here are some ways in which different magnets interact with soda cans:

  1. Neodymium Magnets: These powerful magnets create a noticeable attraction to the soda can. As you bring the magnet close, you can feel the pull between them.
  2. Ferrite Magnets: While not as strong as neodymium magnets, ferrite magnets still exhibit an attractive force towards the soda can. You can see the can slightly move when placed near these magnets.
  3. Electromagnets: By creating a magnetic field using electricity, electromagnets have the ability to affect aluminum cans. When powered on, an electromagnet causes the soda can to vibrate or even crush in slow motion due to the intense magnetic flux.
  4. Magnetic Fields: Even though aluminum is not inherently magnetic, it can become weakly magnetic in strong magnetic fields. When exposed to a powerful magnet, a soda can may exhibit minimal attraction, but not enough to stick firmly.
  5. Nonmagnetic Materials: In contrast to iron and steel objects that readily adhere to magnets, soda cans made of nonmagnetic materials like aluminum do not experience any significant attraction or movement when near most magnets.


After conducting various experiments and exploring the properties of aluminum and magnetism, it is clear that soda cans, made primarily of aluminum, are not magnetic in everyday circumstances.

While aluminum can become slightly magnetic under strong magnetic fieldsthis phenomenon does not occur naturally.

Therefore, you don’t need to worry about your soda can being attracted to magnets or spontaneously tearing apart.
