Q&A

The magnetic field is a physical phenomenon generated by the displacement of electric charges and revealed by magnetic materials.

To isolate the mechanism from the magnetic field of the magnet, it is necessary either to enclose the magnet in a cage of FARADAY, or to enclose the mechanism in it.

The magnetic field passes through everything, walls, concrete, granite, the human body… and cannot be stopped. The only solution to protect yourself from it is to move away from the source.

Yes, magnetic shielding is possible by using materials with high magnetic susceptibility, which concentrate the magnetic field lines so that they remain within the material.

By using a material capable of concentrating the magnetic field lines created in space by magnetic field sources, such as magnets.

MECA MAGNETIC has contributed over the last 10 years to more than 10 national or European scientific projects, some of them multi-year. As such, we have an internal competence to respond to the different stages of calls for tender, to plan, to establish cost structures upstream of the projects, to follow your projects, to exchange regularly with you, and to adapt to the reality of the planning evolutions.

MECA MAGNETIC can help you finalize your magnetic and mechanical designs, in order to adapt as closely as possible to your installation/assembly and magnetic constraints. We can also help you to secure your material supply.

We control the attenuations with our Helmhotz coil or with Gaussmeters. We systematically propose the supply of magnetic value readings made on control washers, coming from the same material batch and having undergone the same heat treatment as the delivered parts.

MECA MAGNETIC is certified ISO 9001 since 2009. This certification, issued by the TÜV and renewed in 2022, certifies that the quality system at MECA MAGNETIC is evaluated annually and judged to be in conformity with the manufacturing requirements of our low frequency magnetic shields.

Yes, we usually do in our line of business. We also carry out pre-series in the parts qualification process. The pre-industrialization phase allows us to validate the various stages of product definition and industrialization.

We check the attenuations with our Helmhotz coil or with Gaussmeters. In most cases, we offer to provide magnetic value readings on control washers, from the same material batch and having undergone the same heat treatment as the parts delivered.
MECA MAGNETIC, also manages the specificities of the customers’ needs and control documents.

Suppliers are located in France and/or in the European Union, which is also a CSR issue for MECA MAGNETIC. They are used to (and/or certified in) the aeronautics and space sector. Their work practices are therefore reliable. These suppliers/subcontractors are evaluated once a year and exchanges for continuous improvement are regular.

Yes, we have a stock of material that allows us to respond within an optimized timeframe. Meca Magnetic is also able to have dedicated and specific stocks for significant series.

MECA MAGNETIC is certified ISO 9001 since 2009 and continues to be involved in this standard every year, in order to demonstrate its capacity and its commitment in customer satisfaction, quality system, management and continuous improvement.
The last audit demonstrated that the processes put in place continue to be demanding and effective. This certification, issued by TÜV, certifies that the management system in place at MECA MAGNETIC has been evaluated and found to be in compliance with the manufacturing requirements of our low frequency magnetic shields. MECA MAGNETIC is also regularly audited by its aerospace customers.

The dematerialized information is managed via our ERP, which allows us to ensure full traceability of data related to products from the customer order, purchases, stocks, production follow-up, quality, accounting…
MECA MAGNETIC rigorously identifies product and/or order and/or quotation changes (index management) and keeps all data securely in accordance with customer/standard requirements.

Yes, when we deem it necessary or upon specific request. When shielding a room or shielded cabins, we carry out these measurements or mandate an independent, certified organization to validate the proper execution of the contract.

Yes, this is possible in France or neighbouring countries.

An instrument emits a magnetic field. When shielding, the magnetic field can be absorbed by a metal shield; this is passive shielding. The magnetic field can also be neutralized by another instrument which emits an opposite magnetic field of equivalent value, thus eliminating the residual field in a limited space: this is active shielding. The skill in shielding is to balance the two solutions, which complement each other when the residual field requirement is very low.

Each time we receive material and before it is put into stock, we follow defined instructions and procedures:
– the material certificate, which includes a laboratory evaluation of the material performance
– the total weight of the delivery
– the dimensions of the plates
– the thickness of the plates
– for room projects we also perform a material permeability test on samples taken after heat treatment

The directive that applies on electromagnetic fields is the European directive of June 2013 (2013/35/EU – https://eur-lex.europa.eu/).

Each European country may have national regulations that are stricter than this European regulation. This is for example the case in France with the Decree No. 2013-1162 – legifrance.gouv.fr Decree No. 2013-1162 of December 14, 2013 which defines a stricter framework for certain sensitive environments (hospitals, schools …).

MECA MAGNETIC’s ISO 9001 v2015 certification has been renewed by the TÜV in April 2022 for 3 years. We have been certified since 2009 and continue to be involved in this standard on a daily basis, in order to demonstrate our ability and commitment to customer satisfaction, the quality system, management and continuous improvement.
The last audit demonstrated that the processes put in place are effective. This certification attests that the management system in place at MECA MAGNETIC complies with the manufacturing requirements of our low frequency magnetic shields. We are also regularly audited by our medical imaging customers.

The information is managed via our ERP, in order to ensure traceability and complete conservation of the data related to the products of the customer order, purchases, stocks, follow-up of production, quality, accountancy…
MECA MAGNETIC rigorously identifies product and/or order and/or quotation evolutions by index evolutions, and keeps all data securely in accordance with the requests of its customers or standards.

Yes, we have a stock of materials for significant series, which enables us to respond within optimized timeframes in order to secure our customers’ flows.

Our operators carry out self-checks which they record in the manufacturing orders. We can also offer to supply magnetic value readings on control washers, taken from the same batch of material with the same heat treatment as the parts delivered.
MECA MAGNETIC also manages the specific needs of customers and control documents.
