Hard drives, speakers, electric motors, many things.
Neodymium magnets are not conductive because they are made of a type of metal called neodymium, which is not a good conductor of electricity.
Refrigerator magnets, car magnets, neodymium magnets are names of small magnets.
Magnets.
Some examples of permanent magnets include neodymium magnets, samarium cobalt magnets, and ceramic (ferrite) magnets. These magnets retain their magnetism without the need for an external magnetic field.
Permenant magnets.
Bar magnets are not typically used in speakers because they are relatively large and heavy compared to other types of magnets, making them less practical for the size constraints of speaker designs. Additionally, bar magnets can lose their magnetism over time due to demagnetization, which could affect the performance of the speaker. Instead, smaller and more powerful magnets, such as neodymium magnets, are commonly used in speakers.
Neodymium magnets are the strongest type of permanent magnets available, with a much higher magnetic strength compared to other types of magnets like ceramic or alnico magnets.
Not all magnets are made of metal. There are various types of magnets, including ceramic magnets (made of ferrite), neodymium magnets (made of neodymium, iron, and boron), and even electromagnetic magnets that are not made of metal.
Neodymium magnets were discovered independently by General Motors and Sumitomo Special Metals in the early 1980s. These magnets are composed of neodymium, iron, and boron, and are known for being the strongest type of permanent magnet available commercially.
Neodymium magnets are the strongest type of permanent magnets commercially available. They have high magnetic strength and are commonly used in applications requiring strong magnetic fields.
Neodymium magnets are the strongest type of permanent magnets available, with a magnetic field significantly stronger than other types of magnets like ceramic or alnico magnets.
