Answer 1

The measurement of the sensitive magnetic instruments are influenced by the external magnetic field. So these instruments need to be shield from external magnetic field, This is done by placing a soft iron core of high permeability around it. The magnetic flux gets established inside the soft iron rather than the sensitive magnetic device and so the device is shielded.

Answer 2

The measurement of the sensitive magnetic instruments are influenced by the external magnetic field. So these instruments need to be shield from external magnetic field, This is done by placing a soft iron core of high permeability around it. The magnetic flux gets established inside the soft iron rather than the sensitive magnetic device and so the device is shielded.

A sensitive magnetic instrument can be shielded very effectively from outside magnetic fields by placing it inside a box of:

wood

plastic

metal of high conductivity

soft iron of high permeability

An example of a perfect diamagnet is a superconductor. This implies that when a superconductor is put in a magnetic field of intensity $B$ , the magnetic field $B_{S}$ inside the superconductor will be such that :

When a diamagnetic substance is inserted in a current carrying coil, the magnetic field inside the substance is:

A diamagnetic material in a magnetic field moves

Diamagnetic material in a magnetic field moves

A material produces a magnetic field which oppose the applied magnetic field, then it is
