Good sized wedge magnet of useful dimensions - and VERY strong as with all the NdFeB magnets. As stated above, 24 of these will fit together to form a ring of 12 inch outer diameter, and 8 inch inner diameter. So they are 2 inches tall, about 1.5 inches across the top, and just over 1 inch across the bottom. They are 1/2 inch thick. North and South poles are located on the opposite 2 inch X 1 inch surfaces. These are ideal for alternator and motor experiments. We have used these in several wind turbine projects.
