     • The pattern of the magnetic field lines inside the coil is straight and parallel to the axis of the coil. On the outside, these lines are similar to that of a bar magnet, moving from the North pole to the South pole. This is because the loops of wire in the coil add their magnetic fields together to form one strong magnetic field.

   What are the lines of magnetic field from a bar magnet?

   • The lines of magnetic field from a bar magnet form closed lines. By convention, the field direction is taken to be outward from the North pole and in to the South pole of the magnet. Permanent magnets can be made from ferromagnetic materials.

   6 days ago · An electromagnet utilises this by using a coil of wire called a solenoid. This increases the magnetic flux density by adding more turns of wire into a smaller region of space. One end of the solenoid becomes a north pole and the other becomes the south pole. The magnetic field lines around a solenoid are similar to a bar magnet.
