The Helmholtz coils have 320 turns each and a mean radius of cm. Arrange the coils parallel to each other, as shown in Fig. 3 , at a mean distance of cm apart. The terminals should be pointing outwards. Arrange the ESR unit, also shown in Fig. 3 , so that the small coil is accurately at the center of the Helmholtz coils. Place the glass tube containing the DPPH inside the small coil. Connect the Helmholtz coils in a series circuit with the AC and the DC power supplies , the ammeter and the resistor as shown in Fig. 2 .
