   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.

   How does a coil of wire produce a magnetic field?

   • A current through the wire produces a circular magnetic field. The magnetic field for a coil of wire is shown below. 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.

   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.

   How does magnetism and electromagnetism occur?

   • Magnetism and electromagnetism occur because of the magnetic fields around magnets and around electric currents. When a current flows in a wire, it creates a circular magnetic field around the wire. This magnetic field can deflect the needle of a magnetic compass. The strength of the magnetic field is greater: if the current is increased.

   What is the shape of the magnetic field in a solenoid?

   • When an electric current flows, the shape of the magnetic field is very similar to the field of a bar magnet. The field inside a solenoid is strong and uniform. The small magnetic field caused by the current in each coil add together to make a stronger overall 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.
