In the Tangent Galvanometer for physical science and physics, investigate magnetic fields produced by an electric current and observe as a current-carrying coiled wire produces a magnetic field.
Investigate magnetic fields produced by an electric current. Students observe as a current carrying coiled wire produces a magnetic field perpendicular to the direction of the current. Students learn that the strength of the magnetic field varies with the number of times the wire is coiled. Complete instructions provided.
