Answer:
5. Solenoid B’s magnetic field is 2.7 times greater than solenoid A's magnetic field.
Explanation:
The magnetic field produced by a solenoid depends on number of coils, the length of the solenoid and the amount of current flowing through the coil.

Current in solenoid B is 2 times greater than the current in solenoid A.

Number of coils in B is 4 times greater than coils in A

Length of the solenoid B is 3 times greater than solenoid A


Thus, solenoid B's magnetic field is 2.7 times greater than magnetic field of solenoid A.
