Save the Date is a 2012 American romantic comedy-drama film directed by Michael Mohan. It stars Lizzy Caplan and Alison Brie . It won the Achievement Award at the 2012 Newport Beach Film Festival and was nominated for the Grand Jury Prize at the 2012 Sundance Film Festival .
The magnet does not have distinct north or south particles on opposing sides. If a bar magnet is broken into two pieces, in an attempt to separate the north and south poles, the result will be two bar magnets, each of which has both a north and south pole. However, a version of the magnetic-pole approach is used by professional magneticians to ...
It is dependent on the volume occupied by the magnetic field extending outside the domain. This energy is reduced by minimizing the length of the loops of magnetic field lines outside the domain. For example, this tends to encourage the magnetization to be parallel to the surfaces of the sample, so the field lines won't pass outside the sample.
The facility houses several magnets, including a 45 Tesla hybrid magnet, which combines resistive and superconducting magnets. The lab's 41.4 Tesla resistive magnet is the strongest DC (continuous-field) resistive magnet in the world, [13] and the 25 Tesla Keck magnet has the highest homogeneity of any resistive magnet. [14]
In combination with neodymium, another rare-earth element, praseodymium is used to create high-power magnets notable for their strength and durability. [54] In general, most alloys of the cerium-group rare earths ( lanthanum through samarium ) with 3d transition metals give extremely stable magnets that are often used in small equipment, such ...
Magnets attached to a vehicle's fuel line have been claimed to improve fuel economy by aligning fuel molecules, but because motor fuels are non-polar, no such alignment or other magnetic effect on the fuel is possible. When tested, typical magnet devices have shown no effect on vehicle performance or economy.
