Nanospheres made of non‐magnetic materials are shown to present non‐conventional scattering properties similar to those previously reported for somewhat hypothetical magnetodielectric particles. We find a wide window in the near‐infrared, where light scattering by lossless submicrometer semiconductor nanospheres is fully described by their induced electric and magnetic dipoles. The interference between electric and magnetic dipolar fields is shown to lead to anisotropic angular distributions of scattered intensity, including zero backward and almost zero forward scattered intensities at specific wavelengths. Optical forces, arising in the intersection region of two standing waves, lead to a complex force field that can rectify the flow of magnetodielectric particles.
