That's a "permanent" magnet.
Many materials which are capable of being effected by a magnetic field will retain some of those properties once its no longer in direct contact with the field. One example is iron. It can become magnetized by being introduced to a magnetic field and then continue to remain magnetic once the source field is removed.
Those are called permanent magnets. Due to their metallic property to exchange electrons between the atoms the material acquires a permanent one sided quantum spin, producing permanent magnetic field.
Magnetic hysteresis is the phenomenon where the magnetization of a material depends not only on the current magnetic field, but also its history. When the magnetic field is applied and then removed, the material retains some magnetization, showing a lag or "memory" in its response to changing magnetic fields. This results in the characteristic hysteresis loop observed in magnetic materials.
The ability of a material to retain its magnetism is known as magnetic hysteresis. It refers to the phenomenon where a material retains some magnetization even after the external magnetizing field is removed.
Yes, ferromagnetic materials lose their magnetic properties above a specific temperature known as the Curie temperature. At this point, thermal energy disrupts the alignment of magnetic domains, causing the material to become paramagnetic, where it no longer retains its permanent magnetism. The Curie temperature varies for different materials, and once the temperature falls below this threshold, the material can regain its ferromagnetic properties.

A permanent magnet is a material that retains its magnetic properties without the need for an external magnetic field. These magnets have their own persistent magnetic field and can attract or repel other objects with magnetic properties. Common examples include fridge magnets and magnets used in speakers.
Magnetic materials are magnetized by exposing them to a magnetic field, such as from a magnet or an electromagnet. This causes the magnetic domains within the material to align, creating a net magnetic field. The material retains this magnetic field even after the external field is removed.
Nickel is a ferromagnetic material, which means it is strongly attracted to magnets and can be magnetized. It has a high magnetic permeability and retains its magnetism well. Nickel is commonly used in making magnets and magnetic alloys due to its magnetic properties.
To make a magnet, a material with magnetic properties (such as iron, cobalt, or nickel) is exposed to a magnetic field. This aligns the magnetic domains within the material, creating a permanent magnet that retains its magnetism. Additional processes like heating or cooling may be involved to enhance the magnet's properties.

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.
A temporary magnet is a material that becomes magnetic when placed in a magnetic field and loses its magnetism when the magnetic field is removed. This differs from a permanent magnet which retains its magnetism without the need for an external magnetic field. Temporary magnets are often made from materials like iron, steel, or nickel.
High coercivity in permanent magnets ensures that they can maintain their magnetization in the presence of external magnetic fields, making them stable and reliable for long-term use. This property also allows the magnetic material to resist demagnetization, ensuring that the magnet retains its magnetic properties over time.
Iron is a metal with high magnetic power. It is capable of being magnetized and retains its magnetism well, making it a common material for magnets and magnetic applications.
