Yes, a magnet can lose its magnetic power when in contact with certain adhesives like Feviquick, which contains solvents that may affect the magnet's material properties. Prolonged exposure to heat generated during the curing process of the adhesive can also lead to a loss of magnetism. However, the extent of this effect depends on the type of magnet and the conditions of use. Generally, it’s advisable to keep magnets away from strong adhesives to preserve their strength.

Double touch method of making a magnet?
The double touch method involves stroking a ferrous material (such as iron) with a magnet in the same direction twice. This aligns the magnetic domains within the material, creating a temporary magnet. The material will only remain magnetic while in contact with the original magnet.
What are the differences between natural magnets and artificial magnets?
magnet which we get naturally from earth is called natural magnet e.g: lodestone.. while magnet made from magnetic material is called artificial magnet ...
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
What does a electromagnet have that a bar magnet does not have?
The bar magnet and the electromagnet act identical. The difference being a electromagnet is a coil of wire that has a power source connect to both ends, this energizes the coil with an electromagnetic field.
What can you conclude if you place the north pole of a bar magnet near the pole of an unmarked magnet and they repel?
That you have placed the magnet towards the northern pole of the unmarked magnet. Like poles retract while opposite poles attract

How is an electromagnet different from a refrigerator magnet?
An electromagnet is a temporary magnet created by passing an electric current through a coil of wire, while a refrigerator magnet is a permanent magnet that can hold items to a refrigerator or other magnetic surface without needing an electric current. Electromagnets can be turned on and off by controlling the electric current, while refrigerator magnets retain their magnetism without the need for an external power source.
Is a magnet a conductor?
A magnet will conduct electricity.

Is a MRI a permanent magnet?
An MRI (Magnetic Resonance Imaging) machine primarily uses a strong, superconducting magnet to generate a powerful and stable magnetic field. While the superconducting magnet itself is not a permanent magnet, it can maintain its magnetic field without continuous power once it is cooled to a superconducting state. However, MRI machines also utilize permanent magnets in some designs, especially in lower-field or portable MRI systems. Therefore, while the main magnet in most MRI machines is not permanent, some components may include permanent magnets.
Is not a permanent magnet?
An electromagnet is a magnet while an electric current is running through the coil. Turn off the current and it is no longer magnetised, and is, therefore, not a permanent magnet.
How is magnetizing an object the opposite of demagnetizing a magnet?
Demagnetizing. Place the magnet at the opposite end of the metal from where you magnetized it. Again, the magnet must make as much contact with the metal as possible. Rub the metal with the magnet in the opposite direction that you used to magnetize it.
What are the that you should not carry while using compass?
A magnet.

How do you make a powerful magnet?
To make a powerful magnet, use a strong magnetic material like neodymium. Shape it into a magnet by applying a magnetic field while it cools down. Finally, the magnet can be magnetized by rubbing it against a magnet or by exposing it to an electrical current.
How do you separate matchsticks from iron scraps?
With a magnet. Iron scraps will be attracted to a magnet, while matchsticks will not. Alternate answer; drop them in a pan of water. If the matchsticks are wood, they'll float, while the iron scraps will sink.
