The magnetic material can attract electromagnetic wave? The magnet can attract magnetic materials? What meaning, thorough point,

Answer:

This is the so-called "Kerr effect"; CD data read computer is the application of the Kerr effect. The range of magnetic materials is very broad, based on its magnetic properties can be divided into: magnetic material, soft magnetic materials, magnetic materials, spin diluted magnetic materials. According to use also can be divided into the guide magnet material for permanent magnet material the information storage materials, such as magnetic core. So far, the magnetic material or human cognition of primary level, but mankind has realized the magnetic human cognition is dark matter, black holes, or unknown key.

The research of electromagnetic wave absorption of magnetic materials is the gyromagnetic materials, chiral materials; electromagnetic vector for chiral helical characteristics. The hand type magnetic material with a band of electromagnetic waves in the microwave range (radar) interaction by Debye absorption and other ways to reduce the reflection intensity of electromagnetic waves to electromagnetic stealth effect. Moreover, the magnet can also make the reflection light (laser) produce a rotating electromagnetic vector;
