A magnet is by definition magnetic. What was a magnet may now be simply a piece of steel or iron, since losing its magnetism makes it not a magnet anymore.
An electromagnet is only magnetic when it has current running through it, and is not magnetic when turned off.
Ferro-magnets, permanent magnets, temporary magnets, and electromagnets. Ferro-magnets are magnets that are magnetic at a higher temperature than room temperature. do not quote me on that. permanent magnets are magnets that are always magnets, they are the kinds you use a lot. Temporary magnets are things that are magnetic in an extrenal magnetic field. Last but not least, electromagnets. Electromagnets are coils of wire around a cobalt, nickel, or iron. When ou run electricity through the wire, the core and wire become magnetic.
the 4 magnetic materials are iron, steel, copper and nickel
Magnets have domains of aligned magnetic moments, resulting in a macroscopic magnetic field, which is not present in non-magnetic materials. Additionally, magnets exhibit magnetic hysteresis, the ability to retain magnetic properties after being magnetized, which is absent in materials lacking magnetism. Lastly, magnets can attract or repel other magnets or magnetic materials, a behavior not seen in non-magnetic materials.
Not all materials can be magnetized permanently because they don't have unpaired electrons in their atomic structure. Only materials with unpaired electrons can align their spins to create a magnetic field and exhibit magnetic properties. Materials like iron, nickel, and cobalt have this property and can be magnetized.
Magnets are made from magnetic materials. These are metals that can be magnetised or will be attracted to a magnet. Most materials are not magnetic, but iron, cobalt and nickelare magnetic. Steel is mostly iron, so steel is magnetic too.
Nearly all.
Yes, all magnets have a magnetic field. When a material becomes magnetized, it creates a magnetic field around itself that attracts or repels other materials. This magnetic field is the reason why magnets can exert force on other magnets or magnetic materials.
Magnets can retain a permanent magnetic field. All atoms have a magnetic field which are randomly arranged in the object. Magnets and ferrous metals can retain or temporarily align the atomic fields, thus they are magnetic.
No, pennies are made from a combination of metals that are not magnetic, such as copper and zinc. Therefore, a penny will not stick to a magnet.
A magnetic field.
I am not entirely sure what you are after, but you might say that:* It is the nature of magnets to be magnetic. Or:* It is the nature of magnets to be surrounded by a magnetic field.

Yes. All magnets of north and south poles. There is no such thing as a magnetic monopole.
Steel is a magnet material, but not all metals are magnetic, like Aluminum.
Magnets are not polar in the same way that molecules can be polar. Instead, magnets have a north and south pole due to the alignment of their magnetic domains. This alignment creates a magnetic field that allows magnets to attract or repel other magnets or magnetic materials.
No, gold is not magnetic and will not stick to magnets. Gold is a non-ferrous metal, meaning it is not attracted to magnets.
Magnets often contain iron, as it has magnetic properties that align with the magnetic field. Aluminum is not typically used in magnets because it is not inherently magnetic.
