   When a wire is looped into a coil, the magnetic field lines circle around each part of the coil, passing through the centre of it. Diagram showing the magnetic field around a flat circular coil. To increase the strength of the magnetic field around the wire it should be coiled to form a solenoid.

   The magnetic field produced by an electric current in a coil of wire can be visualized as the superposition of the magnetic fields of the current loops which make it up. The fields of the individual current loops add inside the coil to produce a strong and fairly uniform magnetic field.

   Sep 12, 2022 · The magnetic field deep inside the coil is generally aligned with axis of the coil as shown in Figure \(\PageIndex{3}\). This can be explained using the result for the magnetic field due to a straight line current (Section 7.5), in which we found that the magnetic field follows a “right-hand rule.”

   How does a coil of wire produce a magnetic field?

   • The magnetic field produced by an electric current in a coil of wire can be visualized as the superposition of the magnetic fields of the current loops which make it up. The fields of the individual current loops add inside the coil to produce a strong and fairly uniform magnetic field. A tightly wound coil is called a solenoid.

   Why is a coil of wire stronger than a bar magnet?

   • The magnetic fields from each of the turns in the coil add together, so the total magnetic field is much stronger. This produces a field which is similar to that of a bar magnet. A coil of wire like this is often called a solenoid. Coil of wire showing magnetic field, which is stronger closer to the coil.

   Why is the magnetic field aligned with the axis of a coil?

   • The magnetic field deep inside the coil is generally aligned with axis of the coil as shown in Figure 7.6.3 7.6. 3. This can be explained using the result for the magnetic field due to a straight line current (Section 7.5), in which we found that the magnetic field follows a “right-hand rule.”

   How does a magnetic coil work?

   • The magnetic field points in the direction of the fingers of the right hand when the thumb of the right hand is aligned in the direction of current flow. The wire comprising the coil is obviously not straight, but we can consider just one short segment of one turn and then sum the results for all such segments.

   What is the radial symmetry of a magnetic coil?

   • Also, it is apparent from the radial symmetry of the coil that the magnitude of the magnetic field cannot depend on ϕ ϕ. Putting these findings together, we find that the most general form for the magnetic field intensity deep inside the coil is H ≈ z^H(ρ) H ≈ z ^ H (ρ).
