... • How do we apply this concept? – Power is supplied to houses everywhere in the developed world. In the power grid, voltage can be as high as 765000V. This power is stepped down to 72000V at your local substation. From here, the power is stepped down to about 220V at a transformer on a utility pole. ...

They are mostly made from the alloy neodymium iron boride (NdFeB) by a sintering process, meaning they are formed with intense heat and pressure. The element neodymium is found in the mineral sands component called monazite, which is mined ...

230007 - EM - Electromagnetism
... We start this chapter with the discussion of Maxwell's equations, no longer restricted to static fields, in integral form and in free space. We show that time dependent magnetic fields are capable of producing electric currents and non conservative electric fields (Faraday's law), and that a new typ ...

... Now we will find the direction of the field. We know the direction of the velocity (east) and the direction of the force due to the magnetic field (up, out of the page). Therefore we can use the second right hand rule (we will use the left hand, since an electron’s charge is negative). Point the poi ...

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.
