Quizplus · Accepted Answer

When an iron core is inserted into an electromagnet, it increases the magnet's magnetic field strength. This is because iron is a ferromagnetic material, meaning it can easily concentrate magnetic fields within itself. Therefore, the magnetic fields generated by the wire coils of the electromagnet get strengthened by the iron core, ultimately making the magnet stronger.
