A solenoid with an iron core is an example of an electromagnet. Turning the current off, causes the magnetism of the iron the quickly disappear.
The strength of the magnetic field depends on the size of the current. A higher current will give a stronger magnetic field.
Moving charges create a magnetic field. This means that a current produces a magnetic field.
