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.
An electric current flowing in a wire creates a magnetic field around the wire, due to Ampere's law (see drawing below). To concentrate the magnetic field, in an electromagnet the wire is wound into a coil with many turns of wire lying side by side.
