Explains how to do simple calculations for the magnetic field generated by the current in a coil. Three worked examples show you how to calculate the magnetic field strength, the amount of current flowing through the wire and the length of the coil. • The magnetic field strength is directly proportional to the number of winding and the current through the coil. The magnetic field strength is indirectly proportional to the length of the coil. • Magnetic field lines show the strength and direction of the magnetic field around a magnet. Magnetic field lines point from the the north end of the magnet to the south end of the magnet, they may not intersect and the density of field lines is proportional to the strength of the magnetic field at that point. • Share this video with the following link: • • Magnetism (6 of 13) Magnetic Field o... • Support my YouTube channel by doing all of the following: • (1) Subscribe to my channel.
