The strength of any electromagnet changes when the current (amperes)
or the number of 'turns' of wire in its wire coil changes. Increasing either
of them makes the magnet stronger.

∙ 12y agoscrap heap magnets are like electromagnets. electromagnets are wire coils usually raped around a soft iron core turns on and off easy . When connected to a DC voltage or current source, the electromagnet becomes energized, creating a magnetic field just like a permanent magnet. The magnetic flux density is proportional to the magnitude of the current flowing in the wire of the electromagnet. By turning on the magnet it creates a magnetic field attracting metals such as iron, nickel, cobalt and some alloys
