Chapter 27 – Magnetic Field and Magnetic Forces

magnetic field  Magnet Shape Impacts Magnetic Field The magnetic field lines of a neodymium magnet, like any magnet, are affected by the magnet's shape In bar and cylindrical The magnetic field of the magnet is strongest at the poles The direction of the magnetic field shows the direction the force would act on another north pole

The shape of the magnetic field depends on the shape of the conductor When the current travels through a wire the field is circular The field is strongest  1 Scalar Potential for the Magnetic Field 25 2 Basics of Spherical Harmonics 26 3 Application of Spherical Harmonics to the Earth's Magnetic Field

Any magnet produces its own magnetic field, can interact with another magnet, and even attracts other magnetic materials It is the reason why an iron nail is field it will be found to be permanently magnetised Experiment 47
