World Strongest Magnets Buy extremely World Strongest Magnets - As a matter of fact, the neodymium magnets that we sell are currently the strongest permanent magnets on the market. Talking about "magnet strength", this means two things: 1. The attractive force or the magnetic field strength 2. The power of resistance to the destruction of [...]
Linear Magnetic Brakes Linear permanent magnet brakes, also known as eddy current brakes, are a fail safe, power free, deceleration system that is used in conjunction with a metal reaction plate. Ceramic or rare earth magnets are bonded to a steel back iron plate. No input power is required. They are used in applications such [...]
Understanding the Basics of a Voice Coil Actuator A voice coil actuator, also known as a non-commutated DC linear actuator, is a type of direct drive linear motor. The name “voice coil” comes from one of its historically first applications: vibrating the paper cone of a loudspeaker. They are currently used for a wide range [...]
Fermilab achieves world-record field strength for accelerator magnet To build the next generation of powerful proton accelerators, scientists need the strongest magnets possible to steer particles close to the speed of light around a ring. For a given ring size, the higher the beam's energy, the stronger the accelerator's magnets need to be to keep [...]
Magnetic Theory and Design 1. Can you explain the difference between coercive force and intrinsic coercive force? The intrinsic coercive force is the coercivity of a magnet material in a closed circuit configuration. A closed circuit configuration means the magnet does not have any exposed poles. Some examples of a closed circuit configuration are a [...]
Over-belt Electromagnetic Separator The type over-belt electromagnetic separator is intended for removal of tramp iron from bulk materials transported on conveyor belts or vibratory feeders. The electromagnetic separator is used to protect of process machines against damage caused by an unwanted piece of ferrous metal and also to recover valuable ferrous scrap from waste materials. [...]
3D-printed Magnets: How can you produce a magnet with exactly the right magnetic field? Today, manufacturing strong magnets is no problem from a technical perspective. It is, however, difficult to produce a permanent magnet with a magnetic field of a specific pre-determined shape. That is, until now, thanks to the new solution devised at TU [...]
Reconfigurable 3D-printable Magnets with improved maximum energy product In conventional magnets, neodymium with added heavy rare-earths is used in order to induce high output and size reduction. But as deposits of heavy rare-earths such as dysprosium (Dy) and terbium (Tb) are disproportionately distributed, it is important to reduce the amount used due to supply issues [...]
The Uses of Magnets Magnets, besides being fun to play with, have many uses. They are used in consumer as well as industrial goods. Let's get to know more about the uses of magnets. Magnets are materials which produce a magnetic field, and have the capability to attract ferrous components like iron, steel, cobalt, and [...]
Magnetizing or Magnetization In magnetizing the magnetic domains inside of a magnet are aligned with the magnetizing field. If the magnetizing field strength is high enough, all the domains will be aligned and the magnet is said to be magnetized to saturation. Magnetizing to saturation is usually recommended as only then are the magnetic properties [...]
Magnetic Losses Reversible Magnetic losses are normal behavior for all magnetic materials. As the remanence of the all the magnetic materials decreases with increasing temperature, the temperature coefficient is negative, it is to be expected that the magnetic field of a magnet also will decrease with an increase of the temperature. However, this decrease of [...]
DRONE MOTOR PERFORMANCE FACTORS / quadcopter motor factors KV - Velocity Constant Theoreticly KV represents the speed at which the motor rotates for every volt applied to the motor. For example if a motor is 2300kv with a 3S quadcopter battery motor applied to its ends then the motor will spin at 2600x12.60 =32,760 rpm [...]
