NMDA receptor. NMDA receptors (NMDAR), glutamate receptors are the predominant molecular device for synaptic plasticity and to control the memory function.
An electromagnet is a type of magnet in which the magnetic field is produced by an electric current. The magnetic field disappears when the current is turned off. Electromagnets usually consist of a large number of closely spaced turns of wire that create the magnetic field.
The Root of Magnetism. A magnet is one of those things that nearly all of us have used, and yet, have no idea how it works. Most people could tell you that a magnet exerts an invisible force on other magnets, but not many people could tell you why.
