What's the theoretical maximum force? At a certain distance & per kg, i guess. How would you go about calculating this?
Source: http://www.llnl.gov/str/November03/Post.htmlTheoretical analyses show that, if required by the application, Inductrack systems can be designed to levitate more than 40 metric tons per square meter of Halbach array, with up to 50-to-1 ratio of levitated weight of a train car to magnet weight. These levitation forces are close to the theoretical maximum that can be exerted by permanent magnets. Actual values achieved in a test run at GA are about 30 metric tons per square meter, in close agreement with the theoretically predicted levitation force for the configuration that was tested.
Permanent magnets are materials that have a magnetic field that stays constant over time. They work by aligning the magnetic domains within the material, creating a strong magnetic field.
The maximum force of a permanent magnet is determined by the strength of its magnetic field, which is influenced by factors such as the material it is made of, its shape, and its size.
Yes, the maximum force of a permanent magnet can be increased by using materials with stronger magnetic properties, increasing the size or shape of the magnet, or by combining multiple magnets to create a stronger magnetic field.
Permanent magnets have a wide range of uses, including in electric motors, generators, speakers, hard drives, and magnetic separators. They are also commonly used in everyday items such as refrigerator magnets, magnetic jewelry, and magnetic toys.
Yes, there are limitations to the maximum force of a permanent magnet. These include the material's magnetic properties, the size and shape of the magnet, and the distance between the magnet and the object it is attracting or repelling. Additionally, extreme temperatures and external magnetic fields can also affect the maximum force of a permanent magnet.
