# Is magnetic field outside the solenoid zero?

Is magnetic field outside the solenoid zero? An intuitive argument can also be used to show that the field outside the solenoid is actually zero. Magnetic field lines only exist as loops, they cannot diverge from or converge to a point like electric field lines can (see Gauss’s law for magnetism).

What is the electric field outside a solenoid? JUST outside the solenoid, the flux is (μ0nat)(πR2).

Why the magnetic field outside the solenoid is uniform? Magnetic field outside a long solenoid can never be zero. Because a solenoid of finite length will have edges and field will come out. However, if we imagine a straigth solenoid of infonite length or a toroid, it will not have edges from where lines of force can come out.

What is the magnetic field inside the solenoid? The magnetic field inside a solenoid is proportional to both the applied current and the number of turns per unit length. There is no dependence on the diameter of the solenoid, and the field strength doesn’t depend on the position inside the solenoid, i.e., the field inside is constant.

## Is magnetic field outside the solenoid zero? – Additional Questions

### Where is magnetic field zero in a solenoid?

Points at which resultant magnetic field is zero are called neutral points. This is because the magnetic field produced by the magnet is neutralised by some other equal and opposite magnetic field.

### Is the magnetic field of a solenoid uniform?

The field lines inside the solenoid are in the form of straight parallel lines. This indicates that the magnetic field is the same at all points inside the solenoid. That is, the field is uniform inside the solenoid.

### Where is the magnetic field uniform in a solenoid?

The magnetic field generated in the center, or core, of a current carrying solenoid is essentially uniform, and is directed along the axis of the solenoid. Outside the solenoid, the magnetic field is far weaker.

### Is the magnetic field formed in a solenoid uniform or non uniform?

The magnetic field inside a solenoid is uniform.

### Is the magnetic field inside a current carrying solenoid uniform or non uniform?

Magnetic field inside a current carrying solenoid uniform as filed lines are straight and parallel to each other, thus lines representing field is also uniform.

### Why are magnetic field is same inside a solenoid?

As the current flowing through the loops in solenoid carry same amount of current, the field lines produced by individual loops join/augment each other to produce uniform magnetic field.

### What is the magnetic field due to current carrying solenoid?

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