What is the difference between a strongly magnetized nail and a weakly magnetized nail?
In an un-magnetised nail there are tiny domains, each in themselves would be a little magnet, however, in a magnetized steel nail the magnetic "domains" tend to be lined up in the same direction. A domain is a tiny magnet because electrons are spinning with the same orientation. Refer to the related link in the Related Links section below for more details.
How will you find out which one is magnet when two identical bars are given one of them is a magnet and the other is a simple iron bar?
One way is to suspend each bar from a string tied around the middle of the bar. The magnetized bar should rotate to orient itself with the Earth north and south magnetic poles. The other bar will just hang there.
When you use a bar to pick up small iron or steel why do you use the end of the magnet?
Magnets have a polarity which is generated by exposing them to a stronger magnetic field during manufacture. They can be polarized through any two faces on the magnet. Typically long skinny magnets are magnetized end to end. Flat magnets are magnetized side to side. Neodymium magnets are relatively strong, and frequently magnetized between flat faces. The magnetic field is very weak on the sides, and very strong at the ends (faces that were polarized).
How can you tell the difference between a bar of iron a bar of copper and a magnet?
Iron is a ferromagnetic metal, and copper is not. Iron will be attracted to the magnet but the copper will not.
How many kg is iron bar?
It depends on the size of the bar.
What is the difference between a magnetized iron bar and an unmagnetized one?
one is magnetized and the other isn't! sorry for a bad answer but i cant find it in my textbook. ps im in 6th grade!

Earths magnetic field can make a magnet out of an iron bar by causing the magnetic domains to?
align in the same direction, creating a magnetic field within the iron bar. This alignment occurs due to the interaction between the Earth's magnetic field and the magnetic properties of the iron, resulting in the iron bar becoming magnetized.
What is the difference between a soft iron bar and magnet structure?
The difference: Unmagnetized iron atoms, are not coordinated to each other, while magnetized are coordinated, like this:nsnsnsnsns, etc, in long parallel lines
An iron bar can be made magnetic?
Yes. Line the bar up pointing north-south, and whang on it with a hammer for a minute or so. If you hold a compass close to it, the compass should align with the bar, whichever direction it is pointing, showing you that the bar has been magnetized.

What is electromagntiusm?
Think that an insulated wire is wound on a soft iron core. Now without any current in the coil soft iron is not magnetized. As steady current flows through the wire then soft iron would become as a bar magnet. This magnetism would last so long as there is current in the wire. Such a magnetism is known as electromagnetism. But there are permanent magnets. Example bar magnets.
What is soft and hard iron?
One can deform a bar of iron elastically i.e. after the forces on the bar are removed , the iron bar will move back into its original, non deformed shape. You can already guess that there is a limit to elastically loading such an iron bar. Too large a force will deform the bar plastically or, in simpler words, forever. Back to flexible. I understand your question is about elasticity and iron has it to a limit.
Is a iron bar a insulator or a conductor?
A iron bar is a conductor
Is an iron bar a conductor or an insulator?
A iron bar is a conductor
Is an iron bar an insulator or a conductor?
A iron bar is a conductor
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become more magnetic.
