How can magnets be used to detect biological molecules?

A new version of the model is updated every five years to address changes in Earth's magnetic field. The current version (WMM2025) was released on December 17, ... The MagLab is the largest and highest powered magnet lab in the world, offering scientists free access to unique instruments and expertise to help advance ... ... magnetic objects. As the Earth spins on its axis, the electric currents of these metals generate a field of magnetism. The strength of this field varies ... A magnetic sensor usually refers to a sensor that converts the magnitude and variations of a magnetic field into electric signals. Magnetic fields, as ...

Scientists have forced a magnetic crystal into a spin liquid state, which may lead to insights into high-temperature superconductivity and quantum computing. Probably the best known and classic application in which we benefit from magnetic forces is the compass. In the end, even our own land is a big magnet. In fact, ... Jan 18, 2010 ... B is magnetic flux density, whereas H is magnetic field intensity. H has units of amp-turn/meter, whereas B has units of weber/turn-meter^2. In ... May 22, 2012 ... “Magnetism is a force, but it has no energy of its own,” says David Cohen-Tanugi, vice president of the MIT Energy Club and a John S. Hennessy Fellow. Magnets can also attract each other, but only if they face in opposite directions. A magnet has two ends called poles; one end is the north pole and the other ...
