... Some metals, for example iron, steel, cobalt and nickel, are magnetic. A magnet will attract them. If you drop some steel pins on the floor you can pick them up using a magnet. A magnetic force is an example of a non-contact force, which acts over a distance. In Figure 5.4, you can see a bar magnet ...

Magnetic susceptibility of L-amino acids in solid state at high
... Abstract: Magnetic molar susceptibilities (χm) are determined for amino acids in high magnetic fields. The magnetization of the solid state form of L-alanine, L-glutamic acid, L-histidine, L-isoleucine, L-tryptophan, and Ltyrosine were measured at 298 K and 310 K using a commercial SQUID magnetomete ...
