... 79. A proton, a deuteron (q = +e, m = 2.0 u), and an alpha particle (q = +2e, m = 4.0 u) are accelerated through the same potential difference and then enter the same region of uniform magnetic field B, moving perpendicular to B. What is the ratio of (a) the proton’s kinetic energy Kp to the alpha p ...

Magnetostatics – Magnetic Flux Density
... From this characteristic of magnetic fields, it is easy to see that the net magnetic flux passing through a Gaussian surface (a closed surface as shown in Figure 3.26) must be zero. What goes into the surface must come back out. Thus we have Gauss’s law for static magnetic fields ...

9J Force Fields and Electromagnets
... An atom consists of a central nucleus with small particles called electrons moving around it. An atom normally has no overall charge because it has the same number of positive and negative charges. When you rub two materials together, electrons may be transferred from one material to the other. If t ...

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.
