iron box
Well... the electromagnet has a magnetic field around it which will then attract the paper clips, depending on how much strength the electromagnet has. Also the current flowing in the coil [wires] will make the nail or the electromagnet magnatise.
trytrytrytrytrytry says iron is magnetic where as steel ios a compound?????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????????? will you eat me??
for an electromagnet, you need a core material with low remnance. That is, when you remove the magnetomotive force (current in the coil) the core will (mostly) demagnetise and let the load or armature go. Iron or silicon steel has this property. Other steel alloys do not necessarily have this property. They have a high remnance which means they remain highly magnetised even wjen the mmf is removed. This is an undesirable property for an electromagnet.
Iron is used in various industries and applications due to its strength and versatility. In construction, iron is used in beams and girders for buildings and bridges. In manufacturing, iron is used in machinery and tools. In transportation, iron is used in vehicles and infrastructure. Additionally, iron is used in the production of steel, which is essential in many industries such as automotive, construction, and appliances.
Iron-59 is used in medicine for diagnostic imaging tests, specifically to study erythropoiesis (formation of red blood cells) by tracking the movement of iron in the body. It is also used in scientific research to study iron metabolism in both normal and diseased states.
Soft iron is used for the core of an electromagnet because it can be easily magnetized and demagnetized, allowing the electromagnet to quickly switch its magnetic field on and off. This property makes soft iron ideal for applications where a temporary magnetic field is needed, such as in electromagnets used in electric motors, relays, and speakers.
If it's an iron box then it's iron
Robert-Houdin used an electromagnet concealed in his clothing to create a magnetic field strong enough to hold the wooden box in place. By positioning the box strategically and activating the electromagnet at the right moment, he created the illusion that the box was magically sticking to the magnet.
Soft iron is used as the core of an electromagnet because it can easily magnetize and demagnetize, enhancing the magnetic strength. It has high magnetic permeability, allowing magnetic fields to pass through easily and concentrate, increasing the overall magnetic ability of the electromagnet.
An iron nail is used to make an electromagnet because iron is a ferromagnetic material, which means it can easily be magnetized and retains its magnetism. When a current flows through the wire wrapped around the iron nail, it creates a magnetic field, turning the nail into a temporary magnet.
The piece of iron inside an electromagnet is called a core. It acts to enhance the magnetic field produced by the electromagnet when an electric current passes through it.
Iron, Nickel, Cobalt
Most metals. eg Aluminium, copper, tin, uranium
electromagnet can be acquired when electricity is passed through the soft iron piece.
Electromagnets are used to separate ferrous metals (containing iron) and attracted to a magnet, from non-ferrous metals (not containing iron) which are not attracted to a magnet.
An iron core helps to concentrate and direct the magnetic field produced by the electromagnet, increasing its strength. The iron core also easily magnetizes and demagnetizes, which enhances the overall magnetic properties of the electromagnet.
Iron is commonly used for the core of an electromagnet due to its high magnetic permeability, which enhances the strength of the magnetic field produced. Additionally, iron is a relatively inexpensive material compared to other options like cobalt or nickel.
