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.
All magnets are made of a group of metals called the ferromagnetic metals. These are metals such as nickel and iron.Each of these metals have the special property of being able to be magnetized uniformly. When we ask how a magnet works we are simply asking how the object we call a magnet exerts itâs magnetic field.ll magnets are made of a group of metals called the ferromagnetic metals.
