Magnetic Field Shield for Electromagnetic Fields and Vehicle Having an Integrated Magnetic Field Shield
First Claim
1. A magnetic field shield for electromagnetic fields comprising:
- a composite sheet (1) formed from at least three layers (1.1, 1.2, 1.3;
1.1, 1.21, 1.22, 1.31, 1.32) arranged one above the other, wherein at least one of the layers is made of electrical steel sheet or electrical steel strip, wherein at least one of the layers is made of sheet steel and at least one of the layers is made of plastic, elastomer, or a combination of plastic and elastomer wherein the at least one layer made of plastic, elastomer, or a combination of plastic and elastomer integrally bonds together the at least one layer made of electrical steel sheet or electrical steel strip and the at least one layer made of sheet steel.

Abstract
The invention relates to a magnetic field shield for electromagnetic fields, preferably in the frequency range of 50 Hz to 200 kHz, essentially comprising a composite sheet formed from at least three layers arranged one above the other, wherein at least one of the layers is made of electrical steel sheet or electrical steel strip. In order to provide at low cost such a magnetic field shield that has low weight and good shielding effect, it is proposed that at least one of the layers is made of sheet steel and at least one of the layers is made of plastic and/or elastomer, wherein the at least one layer made of plastic and/or elastomer integrally bonds together the at least one layer made of electrical steel sheet/electrical steel strip and the at least one layer made of sheet steel.
