Abstract
One embodiment includes an electromagnetic device for generating a magnetic field in a workspace. The electromagnetic device includes an elongated sleeve defining a hollow space and having an external surface, a magnetic core, and an electric coil wounded onto the external surface of the elongated sleeve and configured to generate the magnetic field when energized. The magnetic core has a first end, a second end, and a middle portion that is disposed between the first end and the second end and received in the hollow space. The first end is provided with a core tip that is shaped substantially as a cone and has a cone radius greater than zero.
