Different Materials for Shielding

Electromagnetic energy is produced as soon as electric current travels through a conductor. Its strength relies on the amplitude and frequency of the current. Some energy can be induced in any conductor placed inside this field. Accordingly, spurious coupling may occur between various parts of the system. Sometimes this effect may be reduced by proper placement of electric circuit elements. The vo...

Suitable Shielding Materials for Magnets

During these years we’ve been asked many times that if our Mu Metal is able to shield a magnet. Unfortunately the answer has always been NO. Then have you ever wondered how a magnet can be shielded? Can a magnetic field be blocked so a magnet only pulls on one side? Or do you need to shield a sensitive device from magnetic fields? There is an important point we have to be clear: magnetic shields c...

Mu Metal Shielding Redirects Radiations

Emitted by all kinds of electronic devices, electromagnetic waves exist everywhere. But don’t worry, magnetic shielding helps to protect against these harmful radiations. Unlike our popular belief, magnetic shields actually can’t reduce or block magnetic fields, it works by redirecting the propagation of magnetic field lines so that magnetic flux flows through the walls of the shield itself, resul...

Calculation of Shielding

Much about Mu Metal magnetic shielding was discussed previously, then what is field attenuation? It’s also called shielding factor (S), which is a ratio between the magnetic field strength outside of the magnetic shield (Ha) and the resultant field on the inside of the shield i.e. Ha/Hi (no units) or S = 20 × log(Ha/Hi) (Db). There are many different calculation formulae according to the permeabil...

The Way a Magnetic Shield Works

Many people know that magnetic shields provide protection by stopping or negating unwanted interference from magnetic fields. But most people have no idea how the shield actually works. There are different ways and materials used in magnetic shielding depending on the frequencies and strengths of the magnetic fields. With the purpose of explaining for this instance, we will use passive low frequen...

Applications of Mu Metal shields

You may haven’t noticed but you’d be surprised if you realize how many items you’re using daily or you may encounter in your lifetime which have Mu Metal magnetic shields applied within them. As nowadays we’re living in a society that largely dependent on technology and electronic devices, it’s more and more important to shield the electromagnetic interference emitting from those various kinds of ...

Shielding Applications of Three Nickel-Iron Alloys

Mu Metal is one of a family of three nickel iron alloys widely used to produce magnetic parts and shielding. The three alloys concerned have the following approximate compositions and well known trade names: 36%NiFe widely known as Supra 36, Nilomag36, Radiometal 36, Magnifer 36 50%NiFe widely known as Supra 50, Nilomag 50, Radiometal 50, Magnifer 50 80%NiFe 5%Mo widely known as Mu Metal, Magnifer...

Annealing of Mu Metal – Vacuum or Hydrogen?

Is it better to anneal Mu Metal in a vacuum or hydrogen furnace? This is a question we are often asked… Pure Hydrogen heat treatment will always give better results as it is a true chemically reducing atmosphere and even removes impurities that are below the surface of the material, allowing the grain structure and therefore the magnetic domains to maximize. All Mu Metal manufacturers will recomme...
