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 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.
