Which of the following correctly describes the magnetic field inside a long straight solenoid carrying-current?
- A.The magnetic field is zero.
- B.The magnetic field is uniform and represented by parallel straight lines.Correct answer
- C.The magnetic field is strongest near the ends and weakest at the center.
- D.The magnetic field changes continuously in magnitude from point to point.
Solution
Inside a long straight current-carrying solenoid, the magnetic field lines are parallel straight lines, indicating that the magnetic field is the same (uniform) at all points inside the solenoid.
