magnetic field
... It is sometimes convenient to refer the value of magnetization to unit mass rather than unit volume. The mass of a small sample can be measured more accurately than its volume, and the mass is independent of temperature whereas the volume changes with temperature due to thermal expansion. The specif ...

... Many rocks contain minerals which are slightly magnetic Example: the rock “lodestone” contains the mineral magnetite (Fe3O4). Igneous rocks (generated by cooling and solidifying a melted magma or lava) commonly contain such minerals. (Some Sedimentary rocks have them too) When the magma or lava cool ...

... Spicules and coronal heating are due to magnetic field and happen all the time. Sunspots are also due to magnetic field but they form only when the Sun is (magnetically) “active”. In addition there are more processes on different scales that are due to the magnetic activity of the Sun. See next figu ...

What is magnetism?
... Magnetism is the force of attraction or repulsion in and around a material. Magnetism is present is all materials but at such low levels that it is not easily detected. Certain materials such as magnetite, iron, steel, nickel, cobalt and alloys of rare earth elements, exhibit magnetism at levels tha ...

... (Yes. When the current is switched off, the magnetic field goes away, and the nail is no longer a magnet. Sometimes, the nail will drop most, but not all of the paper clips. In this case, the nail has become a very weak temporary magnet due to the induced magnetic field from the current in the wire. ...
