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 can one determine the poles of the magnetised iron bar?
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
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.
Why is a iron bar placed in a solenoid?
An iron bar is placed in a solenoid to increase the magnetic field strength produced by the solenoid. The iron bar becomes magnetized by the solenoid's magnetic field, enhancing the overall magnetic effect. This is commonly used in devices like electromagnets to amplify their magnetic strength.
What material is suitable for a bar magnet?
Bar magnets are typically made of ferromagnetic materials such as iron, nickel, or cobalt. These materials have the ability to retain a magnetic field when magnetized, making them ideal for creating strong and long-lasting magnets.
What is the difference between a magnetized iron bar and an unmagnetized one?
A magnetized iron bar has its atomic domains aligned in a consistent direction, creating a magnetic field. An unmagnetized iron bar has its atomic domains oriented randomly, resulting in no magnetic field.
If an iron bar is inserted into a wire coil what would happen to the iron bar?
The iron bar would become magnetized when inserted into a wire coil carrying an electric current. This is because the electric current induces a magnetic field in the coil, which in turn magnetizes the iron bar.
If an iron bar were inserted into the wire coil what would happen to the iron bar?
The iron bar would become magnetized by induction through the wire coil. It would temporarily gain magnetic properties while in contact with the coil, but would lose them once removed.
What is the difference between a strongly magnetized nail and a weakly magnetized nail?

How can you magnetise an iton needle permanently using a strong bar magnet?
Rub the iron needle along one direction on the strong bar magnet repeatedly until it becomes magnetized. Make sure to always rub it in the same direction to ensure a consistent magnetic field. This process aligns the magnetic domains within the iron needle, causing it to become permanently magnetized.
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.
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.
If a soft iron bar is introduced inside a current carrying solenoid what will happen to the magnetic field inside the solenoid?
The introduction of a soft iron bar inside a current-carrying solenoid will enhance the magnetic field inside the solenoid. This is due to the soft iron bar becoming magnetized and concentrating the magnetic field lines, making the overall field stronger.
What is the difference between a soft iron bar and magnet structure?
A soft iron bar can be magnetized temporarily in the presence of a magnetic field and loses its magnetism once the field is removed. A magnet structure, on the other hand, retains its magnetism even without an external magnetic field due to its aligned atomic structure.
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.
What is the difference between the earths magnetic field and a bar magnet?
The Earth's magnetic field is generated by the movement of molten iron in the outer core, while a bar magnet is a permanent magnet made of a material that can be magnetized, such as iron. The Earth's magnetic field is much weaker and more complex than that of a bar magnet, which has a consistent north and south pole.
How can one determine the poles of the magnetised iron bar?
To determine the poles of a magnetized iron bar, you can use a compass. One end of the bar that attracts the north-seeking end of the compass needle is the north pole of the bar. The opposite end that attracts the south-seeking end of the compass needle is the south pole of the bar.
