There are a few ways to do this, but the Halbach array, as [wannabemadsci] explains, allows you to make an array of magnets where one side is very strong, and the other side is very weak.

Halbach magnet arrays represent an innovative approach in the design of permanent magnets for nuclear magnetic resonance (NMR) applications. By arranging magnets in a specific, asymmetrical ...

Now, though, DARPA has created a new form of 2D laser phased array that is so tiny and scalable, that ladar could move into the limelight.

2D array of electron and nuclear spin qubits opens new frontier in quantum science Date: August 15, 2022 Source: Purdue University Summary: By using photons and electron spin qubits to control ...

A Halbach array consists of permanent magnets with their poles rotated relative to each other. Depending on how they’re rotated, you can create some useful patterns in the overall magnetic field.

Medusa™ meets this need by epoxy-free integration of submicron-precision 2D fiber arrays and semiconductor or MEMS backplanes.

PITTSBURGH, March 17, 2025 (GLOBE NEWSWIRE) -- Coherent Corp. (NYSE: COHR), a global leader in photonics, announces the launch of its 2D Collimator Array, an advanced optical assembly designed for ...

German physicists have overcome a long-standing limitation of magnetic field design by outperforming the famed Halbach array with a compact setup that delivers cheaper, stronger, and more uniform ...
