The Ampere Rule Apparatus allows students to study the magnetic field around a current-carrying wire. A heavy brass wire with terminals is arranged on a clear plastic base, providing a straightforward setup for demonstrating the relationship between electric current and magnetic fields. The apparatus includes one 45mm compass and six 16mm compasses for mapping the magnetic field. The overall dimensions are approximately 19 x 8 x 10 cm. This apparatus is well suited for physics classroom demonstrations exploring electromagnetism and the right-hand rule.
