Magnets and devices based on their use
Magnets and devices using magnets are very common and can be used both in electronic projects and ordinary DIY jobs. They are also extremely helpful in wall mounting, creating decorations and general gripping of metal elements. They are also great for building more complex projects, such as electric motors or speakers. It is recommended to pay attention to technical parameters when selecting appropriate magnets and elements based on their use. Technical parameters are e.g. durability and power supply needed. Besides, it is worth paying attention to adaptation to the environment where the magnet is destined to be used. E.g., the magnet must be adjusted to the humidity that exists in the target place, because it is necessary to adjust the appropriate corrosion resistance. Each product in our offer is provided with an appropriate specification to help you make the right choice based on these parameters. Should you have any additional questions, please contact the technical department directly and we will be happy to advise you.
What are the advantages of using magnets?
Magnetic elements are not only very useful and versatile, but there are also many advantages of using them. First of all, they reduce wear and tear of mechanical parts, thanks to which devices operating with magnets (locks, jacks, etc.) are much more durable than their mechanical counterparts. To illustrate the strength of magnets, it is worth mentioning that neodymium magnets do not lose their properties for several hundreds of years! Moreover, locks and valves of direct action have opening and closing times faster than any other locks and valves. No wonder that magnets are so widely so willingly used. They are cheap, extremely durable and offer an extremely diverse range of applications. That is why magnetic elements are a must for every DIY enthusiast and electronics enthusiast. The Botland store meets this need and offers many types of magnets and elements operating on magnets, to which you can find detailed specification helping you with making the right choice.
Electromagnets vs. traditional magnets (permanent)
The big difference between an electromagnet and a magnet is that permanent magnets are also electromagnets with a direct current that makes every atom a magnet. The strength of the magnetic field depends on the material of the core, the number of the solenoid wingdings as well as the intensity of the current. If the current strength is high enough, an electromagnet can generate a stronger magnetic field than a permanent magnet. However, the electromagnetism of the electromagnet disappears once the external current is stopped. The mechanism of the electromagnet can only work with human intervention through the activation of a button, while the magnetism of the permanent magnet remains. Permanent magnets are used primarily in assembly and in devices where continuous operation of magnets is required (e.g. magnetic filters). On the other hand, electromagnets are used in systems where the magnet need to operate only at certain moments (e.g. cranes, solenoid valves and generators).
