MAGNETIC SHIELD, PROGRAM, AND SELECTION METHOD
First Claim
1. A magnetic shield comprising:
- a first hollow member that is configured by a first material; and
a second hollow member that is configured by a second material that is different from the first material, the second hollow member is disposed inside the first hollow member, whereina relative magnetic permeability of the first material in the first magnetic field is higher than a relative magnetic permeability of the second material in the first magnetic field is.

Abstract
A magnetic shield including a first layer and a second layer and shielding an environmental magnetic field is obtained by manufacturing the first layer that is configured by a first material and that includes a hollow portion on the inside and the second layer that is configured by a second material that is different from the first material and which is a hollow member and placing the second layer in the hollow portion of the first layer. With the magnetic shield, in regions between the first layer and the second layer, a material in which the relative magnetic permeability at the strength of the magnetic field at a region that is next to the second layer is high compared to the relative magnetic permeability of the first material at the strength of the magnetic field is selected as the second material that configures the second layer.
