HELMHOLTZ COIL HAVING RELAY SYSTEM

PROBLEM TO BE SOLVED: To provide a Helmholtz coil having a relay system, the coil forming firstly a uniform and strong magnetic field or the like and achieving secondly the uniform and strong magnetic field or the like at the excellent cost simply and easily. SOLUTION: The Helmholtz coil is adopted for resonance relay system. Specifically, relay coils 7 and 8 for a pair of independent relay circuits 5 and 6 are disposed at corresponding positions to coils 4 for an AC power-supply side circuit 3. The coils 4 for the power-supply side circuit 3 resonate with a capacitor 9 for the circuit 3, and the relay coils 7 and 8 for both relay circuits 5 and 6 are paired as the Helmholtz coil and resonate with the capacitors 10 and 11 for the circuits 5 and 6, respectively. Representatively, the relay coil 7 for the relay circuit 5 is disposed at the corresponding position to one coil 41for the power-supply side circuit 3, and the relay coil 8 for the relay circuit 6 is arranged at the corresponding position to the other coil 42for the power-supply side circuit 3.
