Ferrite Alnico Bar magnet is an electromagnet that has a north and south pole. Its core is made of magnetic material, typically soft iron. In addition to being used as a permanent magnet in renewable energy and electronics applications, ferrite magnets are also employed in medicine for contrast enhancement in magnetic resonance imaging (MRI).
There are several different types of alnico bar magnets that range from the high-temperature superconductor variety to low-cost alternatives. Each type serves a different purpose or application. To know more about each type please see our article “Different Types of Alnico Bar Magnets”.
Educational Long Alnico Bar Magnet
Magnet size: 50 x 9 x 9 mm. Weight: 38 grams. The magnet is small and portable, very suitable for children’s teaching.
This was small for high school students hands, but their size was okay. I had them sort iron fillings from a mixture using the magnets. They worked, my students liked the 2 colored ends, and tge lab was a success.
