Can You Put Magnets on a Microwave?

Putting magnets on or in a microwave is generally not recommended. While small magnets like those on refrigerator magnets are usually safe on the outside, larger or stronger magnets inside the microwave can disrupt its functioning and potentially cause damage.

Here’s a closer look at the risks and safety precautions for using magnets with a microwave.

Overview of Microwave Function

First, it helps to understand how a microwave oven works. A microwave contains a magnetron that generates electromagnetic waves. These waves are directed into the internal cooking cavity, where they agitate water molecules in food, producing friction that heats the food.

The waves are contained in the metal interior, which acts as a Faraday cage. This prevents the waves from escaping and cooking the food evenly. A mesh screen on the door also helps block escaping waves.

Risks of Putting Magnets Inside a Microwave

The main risk of putting magnets inside a microwave is that they can interfere with the electromagnetic waves used for cooking. The waves need to be focused on the food, and a strong magnet could potentially redirect them.

Magnets, especially ferromagnetic types like those made with iron, could also cause arcing when placed in a high-energy environment inside a microwave. The sparks from arcing could damage the interior.

Larger neodymium magnets may even have enough pull force to distort the door mesh or affect other internal components. So it’s best not to put any loose magnets inside the microwave cavity.

Are Small Magnets on the Outside Okay?

Small magnets on the exterior of the microwave are generally safe. Refrigerator magnets or magnetic clips used to hold notes and recipes are usually too weak to cause any issues.

As long as they are kept away from the door mesh, small magnets on the outside of the frame shouldn’t disrupt the containment of electromagnetic waves inside. Nor will they interfere with the magnetron itself.

But very strong, powerful magnets could potentially affect the function of the magnetron even if placed on the outside. So it’s best to avoid large neodymium magnets on the microwave exterior as well.

Alternatives for Holding Items on a Microwave

Instead of magnets, there are other microwave-safe options to hold items on your appliance:

• Adhesive hooks – Use removable adhesive hooks to hang kitchen towels or pot holders on the side or top away from the door.
• Suction cups – Lightweight suction cups can hold notes and recipe cards on the exterior without magnets.
• Microwave shelf – Many models have integrated shelves that you can use to hold small kitchen items for easy access.
• Wall mount – Consider mounting a mesh metal wall rack near your microwave to hold spices and other cooking items.

Is It Ever Okay to Put a Magnet Inside?

The only scenario where a magnet could potentially go inside a microwave safely is if it is built into a microwave-safe cooking tool.

For example, some magnetic knife strips or stirring tools are designed for microwave use. In this case, the magnet is sealed and insulated so it doesn’t interfere with the oven’s operation.

Never put a loose magnet or magnetic item inside a running microwave. Only use tools specifically designed and labeled as microwave-safe. The manufacturer will ensure any magnetic components are properly shielded.

FAQs

Can you put magnets on a microwave?

It is not recommended to put magnets on a microwave.

Is it safe to put magnets in a microwave?

No, it is not safe to put magnets in a microwave.

What are the potential risks of putting magnets in a microwave?

Placing magnets in a microwave can cause damage to the microwave and disrupt its operation.

Key Takeaways

To summarize the key points on magnets and microwaves:

Placing strong magnets inside a microwave can redirect electromagnetic waves and cause damage.

Small magnets on the outside are generally safe, as long as they are kept away from the door mesh.

Powerful neodymium magnets should not be placed on the exterior or interior.

Alternatives like adhesive hooks or suction cups can hold items without magnets.

The only exception is fully insulated magnetic components built into microwave-safe cooking tools.

So by following basic microwave safety guidelines, you can feel comfortable using your microwave while avoiding any potential risks from magnets inside or attached to the appliance. Keep the interior free of loose magnets and limit external use to small refrigerator-style magnets on the frame away from the door. With these simple precautions, magnets, and microwaves can safely coexist in the kitchen.
