We developed basic magnetic actuators that use the Faraday force by the magnetic field gradient. These actuators can be used in physics experiments for physics or engineering students. A conical coil was made by winding up a copper wire around a polyimide tube; electric current through the coil induces a magnetic field. Using magnetic actuators, students can study the relationship between the magnetic field gradient and Faraday force.
