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.
What is magnetization of iron?
the process of converting iron to a permanent magnet is called magnetization. As iron is a ferro magnetic material it is magnetized by applying strong magnetic field across it , this makes the alignment of all the magnetic dipoles present in iron in the same direction .Even after the external magnetic field is removed they retain their arrangement , thus it becomes a permanent magnet
What do atoms have that makes an object magnetic?
a magnet field..!
What is the process or material that determines what makes a permanent magnet?
The material and process that determine what makes a permanent magnet is the alignment of magnetic domains within the material. When these domains are aligned in the same direction, the material becomes magnetized and exhibits magnetic properties.
What type of metal makes the strongest magnet?
Neodymium is the type of metal that makes the strongest magnet. It is commonly used in making powerful permanent magnets due to its high magnetism and strength.
What is in a magnet that makes it stick to metal?
The magnets both have very strong energy there for connecting boths magnitude
Is there a magnet in an electromagnet?
An electromagnet is a type of magnet in which the magnetic field is produced by the flow of electric current. The magnetic field disappears when the current ceases. Take a look at this Wikipedia page for more information: http://en.wikipedia.org/wiki/Electromagnet
Why is it unlikely that earths core is a permanent magnet?
An electromagnet only retains major magnetic properties when a current is being run through it.AnswerWhether a material makes a permanent or temporary magnet depends on the nature of the ferromagnetic material involved. For example a coil with a steel core will retain much of its magnetic flux density when the current is switched off, whereas a coil with an iron core will lose most of its magnetic flux density when the current is switched off.
What makes a magnet stick to a refrigerator?
A magnet sticks to a refrigerator because the metal of the fridge is ferromagnetic, meaning it can be magnetized. When a magnet is pressed against the fridge, it creates a magnetic field that aligns with the refrigerator's magnetic field, causing the two to stick together.
How is a moving magnet used to create electricity?
makes current flow through a magnet
When a electro magnet flows through a coil of wire wrapped around a bar of iron it makes what?
a magnetic field
Why can't you make soft iron in to permanent magnet?
Soft iron cannot be made into a permanent magnet because it does not have the ability to hold its magnetism once an external magnetic field is removed. Soft iron has a high magnetic permeability, allowing it to easily magnetize and demagnetize, which makes it useful in electromagnetic applications such as electromagnets. Permanent magnets, on the other hand, are typically made from materials with high coercivity, which enables them to retain their magnetism once magnetized.
