New Process Takes Simpler Approach to Rare Earth Magnet Recycling

A new recycling process developed at the U.S. Department of Energy’s Critical Materials Institute (CMI) turns discarded hard disk drive (HDD) magnets into new magnet material in a few steps, and tackles both the economic and environmental issues typically associated with mining e-waste for valuable materials. Ryan Ott, a scientist at Ames Laboratory and a member […]

Small NdFeB Magnets in Smartphones and Personal Electronics

Small NdFeB Magnets in SmartphonesNeodymium (NdFeB) magnets are an invisible part of every smart phone. These tiny magnets are critical to the function of the phone, working quietly behind the scenes inside the phone case.  These internal magnets are typically used in the speaker, receiver, vibration mode motor, taptic feedback motor, and camera auto-focus mechanism. […]

Understanding Coercivity

When we apply an outside magnetic field to a magnetic material, we are forcing it -coercing it- to become magnetized.  Now that it is magnetized, how much of an applied field is required to demagnetize the material?  When we measure the applied field that either magnetizes or demagnetizes the material, we measure the Coercivity of […]

Understanding Remanence

Remanence is the remaining magnetic field found in the material after the applied magnetic field is reduced to zero.  Remanence is derived from the same word as “remainder” or “remaining” so we can think of Remanence as the magnetic field that remains in the material after the outside magnetic field has been released.Remanence is also […]

Understanding Magnetic Permeability

Magnetic Permeability is a value that expresses how a magnetic material responds to an applied magnetic field.  If a material’s internal dipoles become easily oriented to an applied magnetic field, that material is regarded as being a high-permeability material.  If the material’s internal dipoles do not become easily oriented to an applied magnetic field, it is […]

What Are Neodymium Speakers?

Neodymium is an element with specific characteristics that make it particularly well suited for use in speakerconstruction. Speakers operate by using a magnetic field to generate motion in a coil and speaker cone to project an amplified sound signal. In neodymium speakers, the rare-earth element is used as the primary material in the magnets that […]
