Tech Tips: Designing Magnetic Latches to Keep Electronics Secured
By Pavani Gottipati, Manager, Application Engineering, Ansys
Do you know that permanent magnets are behind the action for
your detachable keyboard, the pencil that attaches to your tablet,
and the wireless charging pad that attaches to your phone? Smart
screen covers for phones, tablets, magnetically latching wall-mount
security cameras and countless electronic devices in day-to-day
life rely on permanent magnets for providing the magnetic attaching
mechanism.
For some applications, such as mounted security cameras, permanent
magnets replace mechanical fasteners, such as screws
and bolts. For other applications, such as wireless chargers, the
magnets reduce the wear-and-tear associated with plugging and
unplugging device cables. In every case, well-designed magnetic
attachments for electronics enhance the user experience.
In a recent presentation from software company Ansys, Pavani
Gottipati, Manager, Application Engineering, explores key design
considerations for magnetic latching. Her article explains how a
low-frequency electromagnetic field solver like Ansys Maxwell can
help engineers run sizing and material studies to optimize the force
in latching mechanisms while reducing the cost of the magnetic
latch. This article highlights a few key aspects, the full presentation
is available on the Ansys website.
