Hot Sale U Shape Horseshoe Alnico bar Education Magnets

Alnico magnet is mainly composed of aluminum, nickel, cobalt, copper, iron and other trace metal elements. Its main features are high remanence and high temperature resistance. Bar shape magnets are widely used in teaching and playing by children. Generally, Hard Ferrite or Cast AlNiCo will be used in the Educational magnets, due to lower cost and good property. Many shapes, sizes and colors are available for clients' choice. We usually paint them in red or blue, or we combine them with other material such as metal, plastic. In the meantime, we obey international safe standard. It is no affection to Children's health. We manufacture Educational magnets based on customers' request.

Features

The magnet is small and portable, very suitable for children's teaching.

The north and south poles are clearly visible.

The teaching magnet is specially designed for children's learning.

Its magnetism is very weak and can only absorb small objects such as coins and keys

Two magnets included in each pack can be used to display the attracting and repelling effects of magnets.

Applications

These strong bar magnets are ideal for science projects for class demonstrations and will help students better grasp magnetism and magnetic polarity. Alnico bar magnets with North/South markings designed with high quality components. They are stronger than Ceramic/Ferrite magnets and will surely last for a long time.

FAQ

Q1. What is an alnico magnet?

A1. Alnico magnets are permanent magnets that are primarily made up of a combination of aluminium, nickel and cobalt but can also include copper, iron and titanium. alnico magnets are available in either isotropic or anisotropic versions.

Q2. Are alnico magnets good?

A2. Alnico magnets are also regarded as having very good to excellent corrosion resistance so can be a great choice for many applications that may be at risk of corrosion (iron, although in the alloy, is usually more corrosion resisting but prolonged exposure to water can start to show corrosion signs longer term).

Q3. How strong are alnico magnets?

A3. Alnico magnets produce magnetic field strength at their poles as high as 1500 gauss (0.15 tesla), or about 3000 times the strength of Earth's magnetic field. Some brands of alnico are isotropic and can be efficiently magnetized in any direction.

Q4. Is alnico stronger than neodymium?

A4. There are five main types of permanent magnet material; these are, in order of strength from strongest to weakest, neodymium, samarium cobalt, alnico, ferrite, and flexible rubber.

Q5. Are alnico magnets expensive?

A5. Alnico is a moderately expensive magnet material because of the Cobalt and Nickel content.
