The generation of a magnetic field by an electric current is

The generation of a magnetic field by an electric current is called electromagnetism. When a current carrying wire is made to form a coil around a piece of iron, the result is an electromagnet. Magnetism is produced by the motion of electric charges. When the electric field rapidly changes the magnetic field rapidly changes in return. The use of coils of wires produces a relationship between electricity and magnetism that gives us another magetism called electromagnetism.

Iread this book last year so take this with a grain of salt.gene jumps from the tree to compete with finny due to the fact that gene is always trying to do better than finny. he is put under the grasp of peer pressure due to finny almost forcing him to do this. ever since he first jumped finny kept pressuring him to jump since he thought gene enjoyed jumping.rather than uses this answer you should probably just reread chapters 3-4
