Magnetic Alignment

Position, made physical.

Magnetic alignment uses a ring of permanent magnets to place two objects in exactly the intended position — and to hold them there. In charging systems it guarantees coil alignment; in accessories it turns attachment itself into the interface.

Precision without attention

Good alignment usually costs attention: you look, you adjust, you check. A magnet array does this work physically — the fields guide the object over the last few millimetres and seat it precisely, every time, in the dark, one-handed. Design effort moves from instructing the user to shaping the field: magnet strength, polarity pattern and placement decide how attachment feels.

Holding force is a design decision

Too weak, and the accessory shears off in a pocket; too strong, and removal feels like a fight. The right force depends on mass, surface friction and use: a power bank that rides a phone in a jacket needs a very different figure from a desk mount. These are measurable, testable values — and worth publishing.

Honest limits

• Magnetic attachment depends on both sides: a phone or case without the ring provides nothing to hold.
• Strong magnet arrays must respect proximity guidance for cards and medical devices; responsible products document this.
