In the same way that electric charges create electric fields around them, north and south poles will set up magnetic fields around them. Again, there is a difference. While electric field lines begin on positive charges and end on negative charges, magnetic field lines are closed loops, extending from the south pole to the north pole and back ...

— Magnetic fields may be represented by continuous lines of force or magnetic flux that emerge from north-seeking magnetic poles and enter south-seeking magnetic poles. The density of the lines indicates the magnitude of the magnetic field. At the poles of a magnet, for example, where the magnetic field is strong, the field lines are crowded …

Discover how cathode rays behave in a magnetic field. Instructions. Take a look at the simple set up of a cathode ray tube. Note the negative electrode (Cathode) at one end and a positive electrode (Anode) at the other.As you see, the tube is connected to a high voltage source, which induces the cathode to emit electrons – essentially an electrical current.
