1. They are widely used in research and development, medical technology for sensor positioning, educational tools for demonstrating magnetic properties, and precise holding fixtures in various engineering applications.

The height and base dimensions of a pyramid magnet influence the concentration and dispersion of the magnetic field. A taller pyramid with a smaller base will have a more focused field at the tip, while a shorter pyramid with a wider base will have a more dispersed field.

Strength in magnetic terms refers to the intensity of the magnetic field. Pyramid magnets are not necessarily stronger but provide a more concentrated field at the tip compared to other shapes like discs or blocks, which have more uniform magnetic distribution.

Yes, pyramid magnets can be customised in various dimensions and grades depending on the specific requirements of the project. Customisation can include changes in base size, height, coating, magnetisation direction and magnetic grade. This also means they can be produced to have increased resistance to demagnetisation forces, such as extreme temperatures. 

Neodymium magnets are brittle and can chip or break if allowed to snap together. It’s important to handle them with care, use protective gloves, and keep them away from electronic devices and magnetic media.
