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.
Magnetic field lines of a solenoid electromagnet, which are similar to a bar magnet as illustrated below with the iron filings. A magnet (from Greek Î¼Î±Î³Î½Î®ÏÎ¹Ï Î»Î¯Î¸Î¿Ï magná¸tis lÃ­thos, Magnesian stone) is a material or object that produces a magnetic field.
