A solenoid of length L=1.00 m and radius Rs=2.50 cm and densityof turns n=150 turns/m is first surrounded coaxially by the coil oftotal number of turns Nc1=35 and radius R1=4.50 cm ( as in Fig 2for problem which you have solved during recitation ); 2. then acoil of total number of turns Nc2=18 and radius R2=1.00 cm isplaced coaxially into the solenoid as it is shown in Fig. below.What is the ratio of mutual inductances in situation 1/situation 2.(M_1/M_2)
