Magnets in Speakers The core component responsible for producing sound in audio equipment is the speaker. It is a kind of transducer device that converts the electric signal into an acoustic signal. The performance of the speaker has a great influence on the sound quality, and the magnet in the speaker largely determines its performance. So in

Magnets in the Voice Coil Motor (VCM)
Magnets in the Voice Coil Motor (VCM) A voice coil motor (VCM) is a special form of direct-drive motor. Its working principle is that the energized coil (conductor) will generate force when placed in a magnetic field, and the magnitude of the force is proportional to the current applied to the coil. The motion form of the

How to Measure the Strength of a Magnet?
How to Measure the Strength of a Magnet? Magnets are objects that generate their own magnetic field. Typically, magnets can be divided into two different groups: permanent magnets and electromagnets. Permanent magnets are those objects that are magnetized and will remain magnetized forever. Electromagnets are composed of wire coils. When current flows through, they generate a magnetic

How to Separate Magnets?
How to Separate Magnets Safely? Magnets are very useful and can be seen everywhere in our lives. And some of the magnets such as Neodymium Magnets, are strong magnets and despite their relatively small size, they still have an incredible and surprising magnetic pull. For anyone who has ever gotten their magnets stuck together, it can be

Hazards of Neodymium Magnets
Hazards of Neodymium Magnets Neodymium magnets are very useful but they are not without danger. So before operating the magnet, please read the hazards of neodymium magnets and remember that safety comes first! Risk of Cracking or Chipping Neodymium magnets are super strong. If you bring two magnets close to each other, even small ones,

What is Magnetic Flux (Φ)?
What is Magnetic Flux (Φ)? In the application of magnets, Magnetic Flux (Φ) is an important index to measure the performance of magnets, especially in the fields of motors, audio speakers, and so on. So what is Magnetic Flux (Φ)? In this article, we will try to answer this question. The Concept of Magnetic Flux (Φ)

What Objects Are Attracted To Magnets?
What Objects Are Attracted To Magnets? Magnets are very useful in our lives. For example, we can use magnets to attract iron nails, iron keys, and iron scraps, etc. So in addition to these objects that are obviously composed of iron, what other objects can be attracted to magnets? First of all, let us first analyze

What Are the Differences Between Strong Magnets and Ordinary Magnets?
What Are the Differences Between Strong Magnets and Ordinary Magnets? Many people who are going to buy magnets may have such questions: What are the differences between strong magnets and ordinary magnets? Which type of magnets should I choose? Is it better to buy strong neodymium magnets or ordinary ferrite magnets? So in this article, we

What Are Magnetic Poles?
What Are Magnetic Poles? Many people who are new to the world of magnets will have such a question: what are magnetic poles? In short, the most magnetic part of the magnet is called the magnetic pole. No matter how small a magnet is, it still has two magnetic poles. You can gently rotate a bar magnet on
