How Temporary Magnets Are Made / How Temporary Magnets Are Created As mentioned in previous sections, temporary magnets are created through a stronger magnetic force that essentially transforms an object into a magnet for a short period of time. However, this force will not remain inside of the object after the external magnetic field is [...]
Types of Temporary Magnets and What They are Used For What is a temporary magnet? Temporary magnets are made from soft metals, and only retain their magnetism while near a permanent magnetic field or electronic current. They become magnetized in the presence of a magnetic field. They lose their magnetism gradually when the magnetic field [...]
What is a Temporary Magnet? The topic of magnets is a very intriguing one, to say the least. While scientists have not yet been able to explain the phenomenon of magnetic force and why it exists, there is plenty of information out there that can be taken in on the topic, including the different types [...]
Permanent Magnets Vs. Temporary Magnets When it comes to magnets, there are two main categories: classified as permanent and temporary. While the details and characteristics of temporary magnets were described in the previous section, permanent magnets are worth mentioning as well. In order to give you a better understanding of what exactly a temporary magnet [...]
Bruker Magnet The electromagnet in the Magnet Laboratory consists of a Bruker Magnet B-E 15, and a Heinzinger PTN 125-40 magnet power supply. These can be used to generate magnetic fields of up to about 1 Tesla. The field strength depends on the current and the distance between the poles of the magnet (Air gap). [...]
