These large diametrically magnetized cylinders are great for use with Hall Effect Sensors. The poles are located on the sides of the cylinders, so they will attract each other as shown in the bottom picture.

Neodymium disc magnets are used in thousands of assemblies and products. These high performance magnets can be easily fixed into position using adhesive or pushed into holes and grooves in wood or plastic. Neodymium disc magnets are commonly found in point of sale display units, stationery folders, scale models and industrial applications. Neodymium disc magnets are truly versatile and are used as widely in homemade arts and crafts as they are in high-end technology and engineering applications. Neodymium magnets attract each other with almost twice the force that they use to attract steel objects. They also attract each other through very large distances, even small magnets will attract each other through the thickness of your finger.
