Ben coils a wire to create a solenoid that is 25-cm long with 300 turns. Mak coils a wire to create a solenoid that is 10-cm long with 200 turns. They place their solenoids in otherwise identical circuits so that the steady-state current is the same for each solenoid. Determine the ratio of the magnetic fields of the two solenoids BPh/BF.

Ben coils a wire to create a solenoid that is 25-cm long with 300 turns. Mak coils a wire to create a solenoid that is 10-cm long with 200 turns. They place their solenoids in otherwise identical circuits so that the steady-state current is the same for each solenoid. Determine the ratio of the magnetic fields of the two solenoids BPh/BF.

 
Expert Solution
Step 1

Given-

Length of solenoid first (L1) = 25 cm

Length of solenoid second (L2) = 10 cm

Number of turns in solenoid first (n1) = 300 Turns

Number of turns in solenoid second (n2) = 200 Turns
