Magnet is a substance that can produce magnetic force. We use magnets very commonly in our lives, such as magnets, induction cookers, etc. However, sometimes we need to identify the magnetic strength of a magnet so that we can choose the most appropriate tool. Next, I will introduce to you several methods to identify the magnetic strength of magnets.
First, the magnetic force of a magnet can be easily identified using a steel needle. Place the magnet on the table, and then slowly bring the steel needle close to the magnet. You will find that the steel needle begins to be attracted by the magnetic force and starts to rotate. You can judge the magnetic force of the magnet by observing the speed and trajectory of the steel needle. If the steel needle can be quickly attracted by the magnetic force and rotate, it indicates that the magnetic force is very strong.
Secondly, you can also use a magnet detector to identify the magnetic force of the magnet. The magnetic detector can detect the strength of the magnetic field generated by the magnet, thereby displaying the value of the magnetic force. When using a magnetic detector, you need to place it near the magnet, let it automatically sense the magnetic field, and then move it away. The magnetic detector will display a value, which represents the magnitude of the magnetic force. By the value of the value, you can determine whether the magnet's magnetic force is strong or weak.
Finally, you can also use heavy objects to identify the magnetic force of a magnet. Place the magnet vertically on the table, then place some heavy objects on it and observe whether the heavy objects can adhere firmly to the magnet. If the heavy objects adhere firmly to the magnet, it indicates that the magnetic force is strong.
