... So to maximize this field we need a large wire radius. This means that we should use all the metal into a single turn of wire. This is why the question is flawed: with one single turn we do not have a solenoid! There must be additional restrictions placed on this problem such as a given minimum numb ...

Downloand the Electromagnetism lesson
... Permanent magnets are objects with permanent magnetic fields that give them forces of attraction and repulsion because they contain a constant flow of electric charge. A magnetic field is generated anytime an electrical current flows through a conductor. Electromagnets are objects that produce a mag ...

Strong field dynamics in high-energy heavy-ion
... Why is it important? • Strong EM/YM fields appear in the very early time of heavy-ion collisions. In other words, the fields are strongest in the early time stages. • Indispensable for understanding the early-time dynamics in heavy-ion collisions strong YM fields (glasma) thermalization strong EM ...

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.
