take a block of iron and then coil some wire around it, then attatch it to a power source and your iron block will act as a magnet due to the magnetic field produced by the coil. the more coils you have, the stronger the magnet and vice versa. in order to create a strong magnet you'll need to produce around 8 or 9V of electricity, so a standard 9V battery should work fine.

What distinguishes a permanent magnet from a temporary magnet?
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.
An example of a permanent magnet?
An example of a permanent magnet is a refrigerator magnet. These magnets are made from materials with high magnetic properties, such as iron, nickel, and cobalt, and retain their magnetic field without the need for an external power source.
What you an example of a permanent magnet?
An example of a permanent magnet is a refrigerator magnet. These magnets are made of materials like iron, nickel, and cobalt, which have a strong magnetic field that persists over time without the need for an external magnetic field to maintain it.
How is an electromagnet like a permanent magnet?
An electromagnet is like a permanent magnet in that both can attract objects made of iron or steel. However, an electromagnet can be turned on and off by controlling the flow of electricity through it, while a permanent magnet always produces a magnetic field.
What is the difference between a permanent and non permanent magnet?
Permanent magnets are bar magnets or horse shoe magnets which has magnetism at all times. But non permanent also known as temporary magnets are usually electromagnets which would have magnetism only when current flows through the coil that surrounds it.
Is magnetite a temporary magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
Can iron be made permanent by stroking it with a strong magnet?
No, iron cannot be made permanently magnetic by stroking it with a strong magnet. This process can only magnetize the iron temporarily. To create a permanent magnet, iron needs to be exposed to stronger magnetic fields or undergo specific treatment processes.
Is magnetite a magnet?
No, it's a permanent magnet. It consists of an iron oxide, and iron is a permanent magnet.
When a piece of iron behaves like a magnet when it is touching a permanent magnet that is called?
The process by which a iron piece touching a permanent magnet behaves as a magnet as long as it maintains contact is called magnetic induction. not only does this work when the iron is physically touching the magnet but it works as long as the piece of iron remains under the influence of the magnet. A iron piece attracted to a magnet through a paper with out any physical contact will also behave as a magnet.
What is the permanent magnet?
neodymium-iron-boron
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 distinguishes a permanent magnet from a temporary magnet?

Is Iron is a naturally occurring permanant magnet?
Iron itself is not a permanent magnet, but it is a ferromagnetic material, meaning it can be magnetized. When iron is exposed to a magnetic field, it can become magnetized and retain its magnetism temporarily. However, for iron to be a permanent magnet, it must undergo specific treatment or alloying with other materials, such as in the creation of neodymium magnets or other permanent magnet alloys. In its natural state, iron does not possess permanent magnetic properties.

Why aren't all iron materials permanent magnets?
When a magnet or iron piece is watched under a powerful microscope we will obseve that a magnet or iron is made up tiny tiny pieces which cannot be further divided realistically such small pieces are known as domains. In a magnet all domains are in the same direction due to which it attracts iron. While in a iron these domains are arranged randomly which nullify its magnetism. When a magnet is brousht near an iron matrial all the domains get attracted to the magnet due to which domains in iron get arranged in a particular direction due to wich at that time they act as magnets but as soon as the magnet gets farther the domains again arrange them selves randomly due to which tey do not remain permanent magnets
