The diagram below the magnetic field patterns between two magnets P and Q. These are magnetic materials that are difficult to magnetize but once magnetized they retain their magnetism for a long time. Review of Kirchhoff’s Current Law& Kirchhoff’s Voltage Law. The end of the material in contact with the magnet attains a polarity opposite to the pole of the magnet. This is one of over 2,200 courses on OCW. Reciprocity Theorem. A magnet can undergo self-demagnetization if poorly stored or the process can be influenced externally by giving the dipoles enough energy to overcome the forces holding them in a particular direction. Other magnets produced artificially by man are called artificial magnets. Domains comprise smaller sub –atomic magnets (molecular magnets) called dipoles. Magnetism – HT10 - RJ Nicholas 15 Why do Domains form? Electricity and Magnetism Notes. Find materials for this course in the pages linked along the left.
