Question

What does the divergence of magnetic field lines near the ends of a current-carrying straight solenoid indicate?

Answer 1

Magnetic field lines near a current-carrying straight solenoid indicate:

1. One end of the solenoid acts as the magnetic north pole, while the other acts as the magnetic south pole.
2. The field lines within the solenoid are parallel straight lines.
3. This indicates that the magnetic field is constant throughout the solenoid.
4. That is, the field inside the solenoid is uniform.

Divergence of magnetic field lines near the ends of a current-carrying straight solenoid:

1. The magnetic field is small and appears to diverge outside the solenoid, at the ends, and beyond.
2. This divergence occurs as the distance between the current-carrying solenoid and the sensor increases.
3. A current flowing through it produces a homogeneous magnetic field inside the solenoid or along its axis.
4. The magnetic field is small and seems to diverge beyond the coil or solenoid, that is, at the ends and beyond.
5. The increasing distance from the current-carrying solenoid is the reason for this divergence.
6. The distance from the current carrying conductor and the magnetic field are inversely proportional In other words, magnetic field intensity diminishes with increasing distance.

Hence, the magnetic field lines divergence near the ends of a current-carrying straight solenoid symbolizes that the solenoid acts like a magnet as magnet field lines form the loop around a magnet.
