"Structure" is an imprecise term. So is "magnet," for that matter.
The simplest kind of iron bar magnets have a structure of, well, iron. More complicated rare earth magnets generally have a more complicated crystal structure, but still, there aren't any "moving parts" inside a magnet, it's just whatever it's made of.
The structure of an electromagnet is basically "wire wrapped around a metal core of some kind". The core isn't actually required, but all else being equal an electromagnet with a soft iron core is stronger than one with no core.
atomic structure
it is a magnet having two poles in their ends. they have a wire like structure in the middle.
The strength of a magnet is determined by the alignment and number of its magnetic domains, which are tiny atomic magnets within the material. Factors such as the material used, its atomic structure, and the presence of an external magnetic field can all affect the strength of a magnet.
The magnetism of a permanent magnet is caused by the magnetic alignement of individual atoms in the crystal structure of the ferromagnetic material. You can break a magnet into thousands of pieces and each tiny piece is a magnet with north and south poles. Each piece will attract or repel any of the other pieces depending on how they are oriented to one another.
You can use neodymium magnet (also known as NdFeB, NIB, or Neo magnet) which is the most widely-used type of rare -earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure.
When a magnet cracks, it can lose its magnetic properties and strength due to the disruption of its internal structure. The fracture may cause the magnet to demagnetize partially or completely, depending on the extent of the damage. Additionally, the magnet may break into smaller pieces, which can each retain some magnetic properties but may not be as strong as the original magnet. In some cases, a cracked magnet can also pose a safety risk, as sharp edges may form.
If you looked at a magnet through a microscope, you would see the arrangement of its magnetic domains and possibly the alignment of its magnetic fields. This would give you a closer look at the microscopic structure of the magnet and how its north and south poles are distributed.
Repeatedly hitting a magnet with a hammer may weaken its magnetic force by disrupting its alignment of magnetic domains. The impact could cause permanent changes in the magnet's structure, potentially reducing its overall magnetic strength. Over time, the magnet may lose its effectiveness and ability to attract or repel other objects.
Four common magnetic materials that are strongly attracted to a magnet are iron, nickel, cobalt, and certain alloys of these metals. This is because these materials have unpaired electrons in their atomic or molecular structure, which creates a magnetic moment. When a magnet is nearby, the magnetic field of the magnet aligns the magnetic moments of these materials, causing them to be strongly attracted to the magnet.
A suspended magnet is usually a magnet suspended by a thin thread and allowed to rotate and swing freely. This will align itself to the Earth's magnetic field providing there is no other magnetic or electromagnetic influnence.
No, picking up a paper clip with a magnet is not a physical change. It is a demonstration of magnetic force and involves no permanent alteration to the paper clip's structure or composition.
Objects that are attracted to a magnet, such as iron, nickel, and cobalt, possess magnetic properties within their atomic structure. These materials have unpaired electrons that align with the magnetic field created by the magnet, causing them to be attracted to each other. Other materials, like wood, plastic, and glass, do not possess these magnetic properties and are not affected by a magnet.
