Magnetic field gradient is necessary to attract a piece of iron. As iron is lump collection of magnetic dipoles, its force will be F ? = ? (m ? ? B ?), if magnetic field is uniform, no gradient will be present, so it will not move to neither direction. More intuitive explanation can be made.
how can a magnet get attracted a piece of iron that is not magnetised. Magnets attract iron due to the influence of their magnetic field upon the iron. Before a piece of iron enters the magnetic field of a magnet, the polarization of the iron atoms is random.

Why do magnets only attract iron, nickel and cobalt
Besides cobalt, why does the magnet only encourage iron, nickel objects? The answer to the question: what makes the new magnet attract artificial substances instead of iron, cobalt and nickel? When these materials come close to a real magnet, the magnet induces an additional magnetic field in them, causing them to attract the opposite due to polarity.
Why does magnet attract only iron
Paramagnetic – dipoles are controlled randomly (very low dipole moment)
Diamagnetic – dipole cannot exist (no dipole moment)
Ferromagnetic ~ all dipoles point in the same direction (large dipole moment)
Ferrimagnetic – However, the dipoles are oriented in opposite directions, i.e. when one dipole necessarily becomes the next
Which metals attract magnets
What is 7 magnets? Neodymium iron bars with hole (NdFeB) – permanent magnet.
Samarium Cobalt – (smco) permanent magnet.
Alnico is a permanent magnet.
Ceramic or ferrite magnets Permanent magnets. magnets
temporary – are magnetized in the profile of the magnetic field.

Can a magnet attract Unmagnetized iron
The magnetic field field aligns the magnetic dipoles (electron spins) of the non-magnetized metal to match those of the magnet itself. This makes this piece of iron a substitute for a magnet, and therefore its north or south poles are the same as those of a magnet, and therefore few stick together.
How does a magnet attract a piece of iron
Under the influence of its magnetic field, the original atoms align their electrons with the passing magnetic field, creating iron, which also becomes magnetized. This, in turn, creates an attractive force with respect to the two magnetized objects.
Why is Unmagnetised iron object attracted to a magnet
Iron has charged particles that attract protons in a magnetic field. Iron contains charged particles that attract electrons to a magnet.
How can a magnet attract a piece of iron that is not magnetized
Magnets attract golf clubs due to the effect of their magnetic field on the iron. Before a piece of iron enters the magnetic field of a magnet, this polarization of the iron atoms will be random.
What indicates that a piece of iron is magnetic its attraction to or repulsion from another piece of magnetized iron
What does the attraction or repulsion of your dog to another magnetic piece of iron say about the fact that the characteristic of a piece of iron is magnetic? A magnet attracts a piece of iron and can attract a piece of iron.
Will a strong piece of magnet attract a piece of copper Why
Magnets are generally objects that can attract or transfer metals such as iron to steel. If you rub a steel story with a strong magnetic field, the piece of steel will also become a magnet. It gets magnetized at the end. Other metals like copper, possibly gold, won’t attract if you need magnets.
Why do iron filings arrange themselves in a definite pattern when sprinkled around a magnet A due to force exerted by a magnet within its magnetic field B due to the force exerted by a magnet outside its magnetic field C due to the pressure of the magneti
Why do iron filings line up in almost any order when scattered around the best magnet? happens for the specific reason that each piece of iron filler rod becomes a small magnet and experiences a force in a certain direction in the resulting magnetic field of the magnet.
How does permanent magnet attract Unmagnetized iron piece
When a magnet approaches an already unmagnetized ferromagnetic material, it locally promotes the magnetization of the material with two opposite poles, as in . This has a positive effect on the attraction of the previously unmagnetized material to the magnets.
What happens when a piece of iron is magnetized
If you rub a strip of iron along a magnet, all the north poles of the atoms using the line of iron will point up in the same direction. The force generated by just aligned atoms creates a magnetic battlefield. The piece of iron is equipped with a magnet. Some substances are more likely to be magnetized by the current of the electrical network.
How can a magnet attract or repel another magnet even if they are not touching
All estrus have two ends, commonly referred to as north and north of the south pole region. The decisive factor in whether a magnet attracts or repels is always the pole. The magnets are attracted to each other when the north pole is about to enter the other south pole. When the poles are brought in at once, either from north to north or from south to south, the heat is repelled.
