A method and apparatus for measuring the magnetic field anisotropy of critical currents in conductive wires and conductive tapes having lengths of at least one meter. In one embodiment, the method and apparatus are adapted to measure the magnetic field anisotropy of critical currents in superconducting wires and tapes. The apparatus includes a magnetic field generation assembly that is capable of generating a magnetic field. The magnetic field is orthogonal to a current passing through a conductive wire or conductive tape positioned on an axis of the assembly. The magnetic field generation assembly and magnetic field are rotatable about the axis.
