An electromagnet is a type of magnet A magnet is a material or object that produces a magnetic field. This magnetic field is invisible but is responsible for the most notable property of a magnet: a force that pulls on other ferromagnetic materials and attracts or repels other magnets in which the magnetic field Magnetic fields surround magnetic materials and electric currents and are detected by the force they exert on other magnetic materials and moving electric charges. The magnetic field at any given point is specified by both a direction and a magnitude ; as such it is a vector field is produced by the flow of electric current Electric current can mean, depending on the context, a flow of electric charge or the rate of flow of electric charge (a quantity). The electric charge that flows is carried by, for example, mobile electrons in a conductor, ions in an electrolyte or both in a plasma. The magnetic field disappears when the current ceases.
Electromagnet attracts paper clips when current is applied creating a magnetic field, loses them when current and magnetic field are removed
