What happens if you cut a magnet?

Have you ever wondered what would happen if you cut a magnet in half? Would it still have the same magnetic properties? In this blog post, we will explore the fascinating world of magnets and uncover the truth behind cutting them.

Understanding Magnets

Before we dive into the cutting process, let's first understand how magnets work. Magnets have two poles, a north pole and a south pole, which create a magnetic field around them. These poles attract or repel each other, depending on their orientation.

The Cutting Process

Now, let's imagine you have a magnet and a sharp tool to cut it. As you start cutting, you might expect to end up with two separate magnets, each with its own north and south pole. However, that's not what happens.

When you cut a magnet in half, you don't get two individual magnets. Instead, you end up with two smaller magnets, each with its own north and south pole. This is because the magnetic field is not confined to a specific area of the magnet but extends throughout its entire structure.

Magnetic Field Redistribution

When you cut a magnet, the magnetic field redistributes itself to accommodate the new configuration. The magnetic field lines adjust to form two smaller magnetic fields, each with its own set of poles. This redistribution ensures that the total magnetic field strength remains the same.

It's important to note that the strength of the magnetic field in each smaller magnet will be weaker than the original magnet. This is due to the redistribution of the magnetic field lines and the decrease in the overall magnetic material.

Effects on Magnetic Properties

While cutting a magnet doesn't eliminate its magnetic properties, it does affect its overall strength. The smaller magnets will have a reduced magnetic field and may not be as effective in attracting or repelling other magnetic materials.

Additionally, the cut edges of the magnets may become slightly demagnetized due to the disruption of the magnetic domains within the material. This can further decrease the overall magnetic strength.


In conclusion, cutting a magnet results in two smaller magnets, each with its own north and south pole. The magnetic field redistributes itself to accommodate the new configuration, but the overall magnetic strength is reduced. While the smaller magnets may still exhibit magnetic properties, they may not be as strong as the original magnet.

So, the next time you come across a magnet, remember that cutting it won't give you two separate magnets, but rather two smaller ones. The world of magnets is truly fascinating, and there is always more to discover!
