In Judaism, gratitude is an essential part of the act of worship and a part of every aspect of a worshiperâs life. According to the Hebrew worldview, all things come from God and because of this, gratitude is extremely important to the followers of Judaism. The Hebrew Scriptures are filled with the idea of gratitude.
What is an electromagnet? An electromagnet is a magnet that runs on electricity. An electromagnet works because an electric current produces a magnetic field. If a wire carrying an electric current is formed into a series of loops, the magnetic field can be concentrated within the loops.
An electromagnet works on the principle that an electric current not only allows electrons to flow in a circuit, but also generates a small magnetic field. When a wire carrying electricity is coiled, the magnetic field becomes even stronger. Iron or steel objects surrounded by this coiled electric wire also become magnetized. This combination of electronic energy, coiled wiring and conductive metal object forms the basis of the device. It may be easier to think of an electromagnet as an electron magnet, not an electric magnet. What is relevant is the free flow of electrons in a circuit and their effects on the wire carrying them. It's possible to demonstrate the basic principles using a supply of bare copper wiring, a D-size chemical battery, and an iron or steel nail.
