All electronics and electrical devices emit electromagnetic waves. Magnetic shielding helps to protect against these harmful radiations. Contrary to popular belief, a magnetic shield cannot reduce or eliminate magnetic fields. Made of special materials, magnetic shields help re-direct magnetic field lines, subsequently lowering the field’s influence on the item intended to be shielded.
How HyMu 80 Works
Composed of 80 percent nickel, 4.5 percent molybdenum and the balance iron, HyMu 80 is one of the most celebrated alloys in the electromagnetic shielding arena. Thanks to its unique composition, HyMu 80 has high permeability properties, which in turn account for its high magnetic susceptibility to an applied magnetic field. Due to its physical properties, this alloy can easily absorb the flow of magnetic fields. EMI shielding engineers leverage this very property to redirect radiations away from areas they want to make free of EMI. Generally, a hollow structure is carved out of a HyMu 80 sheet. This formation helps in surrounding the entire area to be shielded, subsequently creating a radiation-free field.
Magnetic shielding is required for a wide range of applications ranging from the small components in your computer to those enormous shielded rooms called MuRooms. This expansive usage necessitates innovative designing for each shielding application. HyMu 80 shielding design should ideally be aimed at optimizing the efficiency of the shield. A good quality shield never uses too many sharp angles and joints. This might make you think that a spherical shape would be ideal for a magnetic shield, but this is not the case. In most cases, a cylindrical shield or a HyMu 80 can (MuCan) is used for better efficiency, and they are also quick and easy to manufacture.
EMI shielding is one of the most crucial aspects of electronic product design. In fact, it can make or break a product’s prospect in the market.
