- B.The field line pattern of the solenoid resembles the magnetic field line pattern of a straight current carrying wire.
- C.The field in the core of the solenoid decreases from one end of the other end.
- D.The field associated with the solenoid can be increased by decreasing the number of turns in the solenoid.
