Shielding

Magnetic shielding is used to block or redirect magnetic fields and electromagnetic fields. This allows sensitive devices, people or even data to be protected from their influence.

Magnetic fields can be generated by magnets or permanent magnets made of ferromagnetic materials such as iron, nickel or cobalt. The resulting magnetic field is a static magnetic field.

Magnetic fields can also be generated by electromagnets. When a current flows through a coil or conductor, a magnetic field is always generated at the same time. If the current is direct current (DC), a static magnetic field is generated. As soon as alternating current (AC) is involved, we speak of alternating magnetic fields.

Magnetic shielding must always be specifically adapted and designed to the existing requirements. The strength and frequency of the magnetic field play a decisive role here. Magnetic field shields are used in a wide variety of areas and are utilised in industry & energy, research, medical technology, the semiconductor industry, electronics and aerospace.
