One purpose of feedback inhibition is to prevent too much of the product from being made. Feedback inhibition balances production of amino acids, the building blocks of proteins. For example, the enzyme threonine deaminase is inhibited by one of its products: the amino acid isoleucine.
A temporary magnet created when current flows through wire wrapped in coils around an iron bar. Heat Energy The movement of thermal energy from warmer to cooler objects.
The coil is made of copper wire - because it is such an excellent conductor (see conducting properties). It is wound onto an armature. The coil becomes an electromagnet when a current flows through it. The armature supports the coil and can help make the electromagnet stronger. This makes the motor more efficient.
