hey friend your answer
simple electromagnet consisting of a coil of wire wrapped around an iron core. A core of ferromagnetic material like iron serves to increase the magnetic field created.[1] The strength of magnetic field generated is proportional to the amount of current through the winding.[.....
Today, there are countless applications for electromagnets, ranging from large-scale industrial machinery, to small-scale electronic components. In addition, electromagnets are used extensively for the sake of conducting scientific research and experiments, especially where superconductivity and rapid acceleration is called for.
In the case of electromagnetic solenoids, they are used wherever a uniform (i.e. controlled) magnetic field is needed. The same holds true for iron-core electromagnet, where an iron or other ferromagnetic core can be inserted or removed to intensify the magnet’s field strength. As a result, solenoid magnets are to be commonly found in electronic paintball markers, pinball machines, dot matrix printers and fuel injectors, where magnetism is applied and controlled to ensure the controlled movement of specific components.
Given their ability to generate very powerful magnetic fields, low resistance, and high efficiency, superconducting electromagnets are often found in scientific and medical equipment. These include Magnetic Resonance Imaging (MRI) machines in hospitals, and scientific instruments like Nuclear Magnetic Resonance (NMR) spectrometers, mass spectrometers, and also particle accelerators....
