Why should magnets never be heated hammered or dropped?
Heating a magnet can cause it to lose its magnetic properties, while hammering or dropping it can disrupt its internal structure leading to a decrease in magnetic strength. It is best to handle magnets gently to avoid damaging them and ensure they maintain their magnetic properties.
How can tungsten magnets be used in industrial applications for their unique properties?
Tungsten magnets are used in industrial applications for their high magnetic strength and resistance to corrosion. They are commonly used in motors, sensors, and magnetic resonance imaging (MRI) machines due to their ability to maintain their magnetic properties at high temperatures.
How do magnets maintain their permanent properties over time?
Magnets maintain their permanent properties over time because the atoms within the magnet are aligned in a specific way that creates a magnetic field. This alignment is stable and does not easily change, allowing the magnet to retain its magnetic properties.
What are four things that dependent on the size of magnotism force?
The distance between the magnets: The force of magnets decreases as the distance between them increases. The size or strength of the magnets: Stronger magnets will have a larger magnetic force between them. The orientation of the magnets: The force between magnets is strongest when their poles are aligned and weakest when they are opposite. The magnetic properties of the materials: Different materials have varying magnetic permeabilities, affecting the strength of the magnetic force.
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 are magnets kept in the keepers?
when magnets are kept loose their magnetic power becomes weak. therefore a non magnetic substance should be kept in between of two magnets while storing them. so that there is no continuous attraction or repulsion between them.

What are the properties and applications of non-metal magnets?
Non-metal magnets, such as ceramic magnets and rare-earth magnets, have properties like high magnetic strength and resistance to corrosion. They are used in various applications like electric motors, speakers, and medical devices due to their ability to generate magnetic fields.
What is the relationship between neodymium and magnetic field strength?
Neodymium is a type of rare earth magnet that is known for its strong magnetic properties. When neodymium magnets are used in a magnetic field, they can significantly increase the strength of the field due to their high magnetic flux density. This means that neodymium magnets can enhance the overall magnetic field strength when placed within it.
Can the strength of natural magnets be increased?
The strength of natural magnets be increased in various ways. Artificial magnetism can be induced so as to increase magnetism.
What is used to store magnets so that they retain their magnetic strength?
Magnets are usually stored in pairs with opposite poles facing each other to reduce demagnetization. They can also be stored individually in plastic, wooden, or cardboard boxes to prevent them from attracting nearby magnetic objects and losing their magnetic strength. Keeping magnets away from heat and strong magnetic fields can also help maintain their strength.
Which temperature of Magnets affects the magnets strength?
The Curie temperature is the temperature at which magnetic materials lose their magnetic properties. If a magnet is exposed to temperatures beyond its Curie temperature, it will lose its magnetism. However, at lower temperatures, the strength of a magnet tends to increase due to a decrease in thermal motion among its magnetic dipoles.
What is true about permanent magnets?
Permanent magnets have their own magnetic field that does not require external electrical current to maintain. They can attract or repel other magnetic materials without losing their magnetic properties. Common materials used for permanent magnets include iron, nickel, and cobalt.
