Core
Electro magnets differs from permanent magnet because it requires electricity. A simple electro magnet consists of an iron rod wrapped in a coil of copper and when electricity flows through the copper, a magnetic field is formed.
The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction. not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet. A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
An apparatus to determine if a piece of iron is a magnet could consist of a small compass and a stand to hold the iron piece. By placing the compass near the iron, if the needle moves and aligns itself with the iron, it indicates that the iron is magnetized. Additionally, the apparatus could include a setup to test for attraction to other magnetic materials; if the iron piece attracts or repels them, it confirms that it is a magnet.
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
If the piece of metal is a magnet it will attract another piece of iron. You should be able to feel this attraction as the two become very close. It's magnetic field can be "seen"( that is the effect) by placing iron filings on a piece of glass and place the magnet beneath the glass. Otherwise it is not a magnet.
It will become an electro-magnet which is an temporary magnet. it is because of the induction property, the magnetic effect gets transfered to the Scale. (it can be any piece of Iron)

You can turn a piece of iron into a temporary magnet by stroking it with a permanent magnet in the same direction multiple times. This process aligns the magnetic domains within the iron, creating a temporary magnetic field.

Iron can be separated from sand using a (electro)magnet.

iron
Because it develops more magnetic power .
Battery/iron rod/copper wire.
When an iron piece is quite away from the magnet ,i.e, not present in magnetic field of the magnet then the iron piece is in neutral state ,i.e, there is no north & south pole . But , as soon as the iron piece interacts with magnetic field of magnet ,i.e, near to the magnet then the north pole of magnet make the nearer part or end of the iron piece south pole & simultaneously other part of iron becomes north pole . Similarly if south pole of the magnet interacts with iron piece then that end/part becomes north pole & other end becomes north pole . Now this iron piece has north & south pole .So iron piece is now converted into magnet which can attract other iron pieces in similar way as explained before .
Separation is easy with an (electro)magnet.
A piece of iron inside a coil forms an electromagnet. When current flows through the coil, it creates a magnetic field that magnetizes the iron, making it behave like a magnet. Electromagnets are used in various applications such as electric motors, generators, and magnetic resonance imaging (MRI) machines.
