Cylindrical Alnico Magnet for physics experiments

Description

The Cylindrical Alnico Magnet, also known as an Alnico rod magnet, cylindrical permanent magnet or laboratory teaching magnet, is designed for demonstrating magnetic fields, magnetic forces and the fundamental principles of magnetism in educational physics laboratories. Manufactured from Alnico, a permanent magnetic alloy based on aluminium, nickel and cobalt, this cylindrical magnet produces a magnetic field without requiring an external electrical power source. Its magnetic properties make it suitable for practical demonstrations involving permanent magnets and ferromagnetic materials. The magnet measures 30 mm in length and 10 mm in diameter, providing a compact cylindrical format for laboratory experiments. Its dimensions allow convenient positioning in compatible physics apparatus and classroom demonstration setups.

The permanent magnetic construction features north and south magnetic poles, enabling students to investigate attraction between opposite poles and repulsion between like poles. During magnetic field mapping experiments, the magnet can be placed near small compasses or beneath a suitable sheet containing iron filings. These arrangements help demonstrate the direction and distribution of the magnetic field surrounding the magnet. The cylindrical magnet is also useful for investigating magnetic attraction and repulsion, allowing students to observe interactions between permanent magnets and suitable ferromagnetic materials such as iron and steel.

In electromagnetic induction demonstrations, the magnet can be moved relative to a compatible coil connected to a measuring instrument. This allows students to investigate how changing magnetic flux can produce an induced electrical voltage. Alnico magnets are valued for their magnetic stability and resistance to elevated temperatures compared with many conventional magnetic materials. However, the maximum operating temperature and magnetic performance specifications for this particular magnet have not been provided. The magnet is suitable for physics education, laboratory magnetism experiments and practical investigations of magnetic interactions in schools, universities and educational science facilities.

Safety Precautions: Handle the magnet carefully to avoid impact damage and unintended attraction to metal objects. Keep it away from magnetically sensitive equipment and implanted medical devices. Avoid exposure to strong opposing magnetic fields or temperatures beyond the manufacturer’s specified limits. This product is intended for laboratory and educational settings and should be used under appropriate supervision.
