What kind magnets are made from materials which retain their magnetic properties for a long time?
Permanent magnets are made from materials that retain their magnetic properties for a long time without the need for an external magnetic field. Examples include neodymium magnets and samarium-cobalt magnets. These materials have high coercivity, which allows them to maintain their magnetism over long periods.
Why is it that permanent magnets can never be demagnetized?
Permanent magnets can never be demagnetized because they are made of materials with strong magnetic properties that align in a way that maintains their magnetic field over time.
How should magnets be stored to maintain their strength and prevent them from losing their magnetic properties over time?
Magnets should be stored in a cool, dry place away from heat and strong magnetic fields to maintain their strength and prevent them from losing their magnetic properties over time.
What distinguishes a permanent magnet from a temporary magnet?
Permanent magnets do not lose their magnetic ability. Temporary magnets, however, gain magnetic properties when they are touched or moved by a permanent magnet. The properties of a temporary magnet dissipates over time after the permanent magnet is removed.
Are permanent magnets truly permanent, or do they eventually lose their magnetism over time?
Permanent magnets are not truly permanent and can lose their magnetism over time due to factors such as exposure to high temperatures, physical damage, or demagnetizing fields.

Element used to make permanent magnets?
Iron, cobalt, and nickel are commonly used elements to make permanent magnets. These elements have magnetic properties that allow them to retain their magnetism over a long period of time.

What are the different types of magnet?
bar magnet, horse shoe magnet,ball ended magnet and cylindrical magnet.I recomend doing the iron shavings and bar magnet experiment.x.x TRY IT .There are 3 types o magnets parmanent, temporary, and electromagnets.you can also use water andblue food colloring to create a magnetic field.Bar Magnet, horseshoe magnet etc
Do permanent magnets wear out over time?
No, permanent magnets do not wear out over time. They can lose some of their magnetism due to external factors, but they do not degrade or wear out like other materials.
What metals can form a permanent magnet?
Iron, nickel, and cobalt are the most commonly used metals for creating permanent magnets. They have strong magnetic properties and can retain their magnetism over a long period of time. Other metals like neodymium and samarium can also be used to create powerful permanent magnets.
What are the three classification of magnets?
Permanent MagnetsPermanent magnets are those we are most familiar with, such as the magnets hanging onto our refrigerator doors. They are permanent in the sense that once they are magnetized, they retain a level of magnetism. As we will see, different types of permanent magnets have different characteristics or properties concerning how easily they can be demagnetized, how strong they can be, how their strength varies with temperature, and so on.Temporary MagnetsTemporary magnets are those which act like a permanent magnet when they are within a strong magnetic field, but lose their magnetism when the magnetic field disappears. Examples would be paperclips and nails and other soft iron items.ElectromagnetsAn electromagnet is a tightly wound helical coil of wire, usually with an iron core, which acts like a permanent magnet when current is flowing in the wire. The strength and polarity of the magnetic field created by the electromagnet are adjustable by changing the magnitude of the current flowing through the wire and by changing the direction of the current flow.
Different between temporary magnet and Parmanent magnet?
A temporary magnet can be magnetized or demagnetized easily, while a permanent magnet retains its magnetization over a long period of time. Temporary magnets are usually made of soft magnetic materials like iron, while permanent magnets are made of hard magnetic materials like neodymium or ferrite. Temporary magnets require an external magnetic field to maintain their magnetism, whereas permanent magnets do not.
What is the difference between permanent and tepoary magnets?
Temporary magnets are created using an electrical field. Once the current is switched off, it is no longer magnetic. A permanent magnet on the other hand, such as the common Ferro-ceramic magnet remains magnetic all the time because it was manufactured with all of its iron particles facing the same way.
