Not exactly.
For near field tags, a mu-metal shield provides some protection.
For far-field tags, the typical foil/screen Farraday cage provides protection.
Something is either magnetized or not magnetized. There is no such thing as "unmagnetized magnetic" material.
A simple block of magnetized iron is called a magnet.
Magnetization does not affect the mass of the material being magnetized. All the magnetizing field does is align the magnetic domains of the material being magnetized. No matter or mass is added, or "created out of energy" or the like. Nothing changes except the orientation of magnetic domains within the material being magnetized.
Mainly from the electrons, rotating around the nucleus. If the material is magnetized, then it is because several atoms are aligned in the same direction.Mainly from the electrons, rotating around the nucleus.

If the material is magnetized, then it is because several atoms are aligned in the same direction.
When an object is magnetized, the alignment of the electrons within the atoms of the material becomes coordinated, creating a magnetic field. This alignment allows the material to exhibit magnetic properties such as attracting or repelling other objects.
Yes, aluminum can block RFID signals.
Yes, aluminum foil can block RFID signals.
Yes, aluminum foil can effectively block RFID signals.
A block diagram of the RFID or radio frequency identification can be found online at places like TI.com and Colorado.edu.

The magnetic domains of an unmagnetized material will be pointing in random directions, which is why it is appearing to me unmagnetized. In a magnetized material, they move from north to south.
Yes, aluminum foil can effectively block RFID scanners because it acts as a barrier to the radio waves used by the scanners to communicate with RFID tags. Placing an RFID card or device in an aluminum foil pouch can prevent it from being scanned.

No, copper cannot be magnetized because it is not a ferromagnetic material.
The domains in a magnetic material is aligned unlike the non-magnetic material which is scattered
To effectively block RFID signals using aluminum foil, wrap the RFID card or device in multiple layers of foil to create a barrier that prevents the signals from being transmitted or received. Make sure the foil completely covers the card or device to block the signals effectively.
