Magnetic Shielding in the Information Age

Magnetic Shielding in the Information Age July 21, 2017

We live in a society that is built around advancements in technology and convenience that is rendered to us through the application of mobile technologies. Smartphones, tablets, laptops, Bluetooth technology, watch technology, heck, even garage door openers (and so much more). Handheld technologies are not new, and, in fact, they’re expanding into more and more facets of our life each and every day.

Here’s where things get tricky (depending on how you look at them): All of these conveniences afforded to us have challenges that must be met for operative efficiency, as well as secure communication.

What’s that you say?

Well, these electronics that guide us through our daily routines emit electromagnetic waves – causing electromagnetic interference (EMI) – which is a component of their makeup that needs to be addressed to ensure not only operative success, but human/operator safety as well.

That said, they’re all in need of magnetic shielding to protect against the radiation that permeates in the form of the aforementioned electromagnetic waves. Electromagnetic compatibility (EMC) is a major factor in the design and application of electronic devices to control the unintentional generation, propagation, and reception of this potentially harmful electromagnetic energy. Magnetic shielding is a custom designed solution, and depending on the application, is made of special, scientifically rendered materials that help redirect magnetic field lines which in turn eliminates magnetic interference with other present technologies giving off their own electromagnetic fields.

If you’re in the business of creating new, groundbreaking technologies, you’re likely hip to importance of magnetic shielding. We don’t doubt that for a second. The question is:

How are you combating the emittance of electromagnetic interference (EMI)?

You can’t just take a pass and hope for the best. You have to combat the issue with a magnetic shield that is proven to work. If you’re not, your idea is going to get shot down before it gets purchased and pushed to the manufacturing phase.

The amount of reduction that your magnetic shield conjurs up depends on specific variables such as:

  • Material used
    • Chemical makeup of the material
    • Thickness of that material
  • Size of the shielded volume
    • Frequency of the fields of interest related to that very “volume”
  • Size, shape and orientation of existing apertures in your shield

One great solution / material we use to help our customers with their magnetic shielding needs is mumetal. The material conforms to spec ASTM A753 Alloy Type 4 an MIL N 14411 Composition 1 and is composed of 80% nickel, 4.5% molybdenum and a balance of iron. Mumetal is far and away the best and most coveted solutions in the magnetic shielding industry.

It’s okay if you’re not steeped in a well of knowledge related to mumetal and/or magnetic shields. That’s where trusted, proven companies like MuShield come in – helping you get your technologies to market. If you’re in need, let’s have a conversation. You can look us up on your mobile phone, if you’d like. We’re sitting there, waiting, right in the palm of your hand.
