An electrically charged particle enters into a uniform magnetic induction field in a direction perpendicular to the field with a velocity $ v $ . Then, it travels

A steady current flows in a long wire. It is bent into a circular loop of one turn and the magnetic field at the centre of the coil is $ B $ . If the same wire is bent into a circular loop of $ n $ turns, the magnetic field at the centre of the coil is
