This is a property referred to as the hysteresis of the magnetized material. It is not actually possible to make such a prediction without a lot more information. In this case, in particular, since you haven't identified the material. Suffice to say that, based on the very limited information in your question, the best answer would be "always."

What is keeper and its use in magnetism?
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
What happens when you touch a piece of iron to a permanent magnet?
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
What type of magnet has iron in it?
magnetism
Does putting a magnet in the water for 60 minutes make the magnet lose its magnetism?
No it wont but if the water is hot then it will lose its magnetism
What is the difference between permanent pole and temporary pole?
a Temporary Magnet lose its magnetism quickly, a Permanent Magnet is hard and it keeps it magnetism
What is keeper and its use in magnetism?
A keeper is a iron or a steel bar that is used to retain the strength of magnet.
Permanent and temporary magnets?
A temporary magnet is something that has been magnetized that won't stay a magnet for long, such as a paperclip that you have rubbed with a magnet. A Permanent magnet is usually a Lodestone that is found naturally or is manufactured by a company. Permanent magnets are always magnetic.
What does the electro magnet prove about electricity?
An electro magnet proves that Electricity and Magnetism always co-exist in nature
How long does it take for a magnet to lose its magnetism?
The time it takes for a magnet to lose its magnetism can vary depending on factors like the type of magnet and how it is used. In general, permanent magnets can retain their magnetism for many years or even decades if they are not subjected to extreme conditions. However, some magnets may gradually lose their magnetism over time due to factors like exposure to high temperatures or physical damage.
What happens when you touch a piece of iron to a permanent magnet?
When you touch a piece of iron to a permanent magnet, the iron can become magnetized temporarily because it can align its domains with the magnetic field. However, once the iron is removed from the magnet, it will lose its magnetism over time. The iron itself does not retain a permanent magnetism like the original magnet.
What is a hard magnet?
Hard magnets are permanent magnets that do not require electricity to retain their magnetism and are not easily demagnetized. They are magnetically charged naturally and can be artificially, too.
What Are words that have root word magnet?
Magnet-ic Magnet-on (also the name of a Pokemon)
What propeties do a magnet have?
magnetism
Is iron a permanent magnet?
No, iron is not a permanent magnet. It can be magnetized in the presence of a magnetic field but will lose its magnetism once the external magnetic field is removed. Permanent magnets, on the other hand, retain their magnetism without the need for an external magnetic field.
How do you magnetize a Quarter?
To magnetize a quarter, you can rub a strong magnet along its surface in one direction for several strokes. This aligns the metal's magnetic domains, which can induce a weak magnetism in the coin. It's important to use a strong enough magnet, like a neodymium magnet, for effective magnetization. However, keep in mind that the effect will be temporary and the coin will not retain strong magnetism.
What is the difference between a strong magnet and a weak magnet?
the domain strength is much stronger in a magnetised nail. when you have a weak nail, there is no magnetic force. sometimes they can repell. this is what i think and i always know best thank you
Magnetism is stronger at what place of the magnet?
A magnets magnetism is strongest at the poles.
