Question

Is the magnetic field inside a current-carrying solenoid constant at all points?

Answer 1

Magnetic field

1. A magnetic field is a region or place where a magnet exerts its influence. Magnets come in a variety of shapes and sizes.
2. Magnets such as bar magnets, rod magnets, horseshoe magnets, ring magnets, and others. All magnets have two poles: the North Pole (represented by the letter 'N') and the South Pole (represented by the letter 'S').

Magnetic field lines that surround the current-carrying solenoid.

1. A solenoid is a coil comprising several circular turns of insulated copper wire wrapped tightly in a cylinder shape.
2. The field pattern is comparable to that of a magnetic field around a bar magnet. The solenoid's one end acts as a magnetic north pole, while the other acts as a magnetic south pole.
3. Inside the solenoid, the magnetic field lines are parallel to each other forming a uniform field strength which indicates that the magnetic field is the same at all points inside the solenoid.

Hence, the magnetic field produced by a current-carrying solenoid is the same at all points inside it.
