Current can produce magnetism.
... Motors use electromagnets. Because magnetism is a force, magnets can be used to move things. Electric motors convert the energy of an electric current into motion by taking advantage of the interaction between current and magnetism. There are hundreds of devices that contain electric motors.

Experiment 5: Magnetic Fields of a Bar Magnet and of the Earth
... earth’s field), select AXIAL, and push the TARE button while the sensor is far away from the bar magnetic. Start taking data, and move the sensor towards one end of the bar magnet, with the probe on and parallel to the magnet axis. (Some find it easier to hold the sensor fixed and move the magnet.) ...

... If a piece of iron is inserted in the solenoid, the magnetic field greatly increases, because the iron becomes a magnet. The resulting magnetic field is the sum of the field due to the current and the field due to the iron, and can be hundreds or thousands time of the field due to the current alone. ...

Making a Magnet - Siemens Science Day
... Three things are needed to create a simple electromagnet: electricity, a copper wire, and a ferromagnetic material, such as an iron nail. Ferromagnetic material is any material that can be attracted by magnets. When you attach the copper wire to the positive and negative ends of a battery, electric ...

... These are opposite currents - they repel! Iron naturally has small spatial regions (domains) that each act like small magnets, like on the previous page. They tend to be randomly oriented. So iron is not normally a magnet. (E.g, a normal nail doesn't stick to the fridge). But if you put iron into a ...
