Sketch magnetic field lines for three different cases shown (on your own sheet). (a) a magnetic bar, (b) straight wire with current; (c) loop of current on a wire.  Direction of currents are indicated in the figures.  Draw at lease two magnetic field lines for each case, including the directions of magnetic field. (If you can’t draw on your note, you may use words to describe them.)   HTML EditorKeyboard Shortcuts

Bar Magnet

In physics, magnetism is a phenomenon exhibited by a magnetic substance that exerts either attractive or repulsive force. A bar magnet is either a rectangular or round and hollow fit comprised of ferromagnetic materials and has a fanciful attractive field surrounded by it.
