ELECTROMAGNETISM and MAGNETIC FIELD LINES BY: IMENDOZA Electromagnetism… A magnet created by electric current flowing in wires Electricity & Magnetism… Every time an electric charge moves, a magnetic field is created. Every time a magnetic field varies, an electric field is created. Magnetic Field… The magnetic force that surrounds a magnetic object at all points Magnetic Field Lines… The arrows used to show the direction of the magnetic force in a magnetic field Magnetic Field Lines… Always point away from a magnet’s NORTH pole Always point toward a magnet’s SOUTH pole DRAWING Magnetic Field Lines… Leaves from the NORTH pole and ends at the SOUTH pole Magnetic Field Lines in Multiple Test Magnets… Strength of Magnetic Forces… If field lines are close together, the force is stronger. If the field lines are farther apart, the force is weaker. At which point is the magnetic field line stronger? Explain your answer. A B North-South Attraction Magnetic Field Lines Opposite poles (S-N or N-S) = ATTRACT N-N/S-S Repulsion Magnetic Field Lines… Like poles (N-N or S-S) = REPEL
