Simple break one of the rods apart and see if it sticks together if it does it's a magnet if it doesn't then it isn't one
You can identify which iron piece is a magnet by bringing a small iron nail close to each piece. The one that attracts the nail is the magnet. Alternatively, you can observe which iron piece attracts small metal objects like paper clips or pins.
The strongest magnetic area of a bar magnet is the sides.
Not all metal objects that conduct electricity are attracted by a magnet. Magnets primarily attract ferromagnetic materials, such as iron, cobalt, and nickel. While conductive metals like copper and aluminum can carry electric current, they are not ferromagnetic and thus are not attracted to magnets.
You can perform a simple test by bringing a compass close to the metal bar. If the compass needle moves or aligns with the metal bar, then the bar is likely a magnet. Another test involves observing if the metal bar can attract small metal objects like paper clips.
One common procedure to identify metals is through a flame test, where the metal sample is heated in a flame and the characteristic color of the flame produced can help identify the metal. Other methods include using reactivity with acids or other chemicals, measuring density, conducting an electrical conductivity test, or using spectroscopic techniques to analyze the metal's atomic structure.
By brushing it against a metal
You could use a magnet to separate a collection of metal objects from a tomb. Iron object and other ferrous metals will stick to the magnet while some other types of metals will not.
They magnetic and magnets are attracted to metal objects. since the refrigerator has metal in it the magnet sticks to it.
Separation is easy with an (electro)magnet.
A magnet can push or pull objects with metal components due to its magnetic field.

just about everything except most furniture
Fridge magnets work by using a magnetic force to stick to metal surfaces. The magnet has two poles, a north pole and a south pole. When the magnet comes into contact with a metal surface, the magnetic field of the magnet interacts with the metal, creating a force that holds the magnet in place. This force is strong enough to keep the magnet attached to the metal surface, allowing it to hold up papers or other lightweight objects.
The strongest magnetic area of a bar magnet is the sides.
An electromagnet would generally be better for lifting heavy metal objects as its magnetic strength can be easily controlled by adjusting the electrical current. A permanent magnet may not have sufficient magnetic strength to lift heavy objects, and it does not offer the flexibility of adjusting its magnetic force.
The electromagnetic crane has a huge electric magnet that is operated by an electrical current. When the electricity is switched on the magnet becomes magnetized for allowing metal objects to be picked up just like an ordinary magnet, but when electricity is turned off the metal object fall away.
To test the strength of a magnet, you can use a compass to see how strongly the magnet attracts or repels the needle. The stronger the magnet, the more the needle will move. You can also compare the magnet's ability to pick up metal objects of different weights to gauge its strength.
