... Current on one side of the loop flows in the opposite direction to the current on the other side of loop. So, the two sides gets deflected in opposite directions, as shown; hence it turns. After a half turn, the sides have reversed, so deflection is in the opposite direction – makes coil turns back. ...

... we introduce new law called LAW OF NATURE 1 which unifies scalars and vectors. Since physics always seeks unification, so we unify scalars and vectors by using new law which is initiated from Maxwell’s equations. Keywords: Law of nature 1, Maxwell’s 2nd equation, moving charge, magnetic current dens ...

... Magnets are surrounded by magnetic fields and attract certain metals (iron, nickel, and cobalt). This magnetic effect comes from a special alignment of the atomic structure of the material. All magnets have two poles, a north pole and a south pole. It is impossible to have a singular magnetic pole; ...

Magnetism
Magnetism is a class of physical phenomena that are mediated by magnetic fields. Electric currents and the magnetic moments of elementary particles give rise to a magnetic field, which acts on other currents and magnetic moments. Every material is influenced to some extent by a magnetic field. The most familiar effect is on permanent magnets, which have persistent magnetic moments caused by ferromagnetism. Most materials do not have permanent moments. Some are attracted to a magnetic field (paramagnetism); others are repulsed by a magnetic field (diamagnetism); others have a more complex relationship with an applied magnetic field (spin glass behavior and antiferromagnetism). Substances that are negligibly affected by magnetic fields are known as non-magnetic substances. These include copper, aluminium, gases, and plastic. Pure oxygen exhibits magnetic properties when cooled to a liquid state.The magnetic state (or magnetic phase) of a material depends on temperature and other variables such as pressure and the applied magnetic field. A material may exhibit more than one form of magnetism as these variables change.
