Many items in our daily lives possess the property of attracting magnets, including magnetic bricks. So, what is the secret behind magnetic bricks, and why do they attract magnets? The answer lies in their internal composition. Magnetic bricks contain a certain proportion of magnetic materials, such as iron, cobalt, and nickel. These materials can be magnetized under the influence of a magnetic field, thus interacting with a magnet. When we bring a magnet close to a magnetic brick, the magnet's magnetic field acts on the magnetic materials inside the brick, causing them to magnetize and attract the magnet.
