| Contd. -2- EFC1/21.7.26. -2- We ourselves do not think there is a great deal in coils with nearly closed magnetic circuit. In any case if there is, the longer a straight coil is made, the more nearly it approaches a similar condition.(magnetically). In connection with our trouble with contact points we have answered Mr. Olley's letter Cy2/Ell.6.26 in our EFC2/T30.6.26 attached. EFC. | ||
