Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFThe correct answer is "Parallel straight lines".Key Points
- Straight parallel lines make up the field lines on the inside of the solenoid.
- The south pole to the north pole inside the solenoid and the north pole to the south pole outside the solenoid is connected by straight lines that are perpendicular to the axis of the solenoid.
- This suggests that the magnetic field is constant (i.e., the exact same at every position inside the solenoid) inside the device.
- Electromagnets are created using the magnetic field of a current-carrying solenoid.
Additional Information
- An electromagnet known as a solenoid creates a regulated magnetic field using a helical coil of wire whose length is significantly higher than its diameter.
- When an electric current is run through the coil, it can create a consistent magnetic field inside a defined region of space.
- A solenoid's helical coil does not always have to circle around an axis that is in a straight line.
