Magnetic Fields

Rules For Drawing Magnetic Fields 1) Arrows will always leave the north side and go to the south side. 2) Field lines will never cross 3) The closer the lines are the stronger the magnetic field is

Draw what you think the magnetic field will look like for this horseshoe magnet

How to draw a magnetic field Draw a dot somewhere near the magnet and place the center of compass over the dot. Draw a dot at the location of the arrow head (or tail) of the compass needle. Move the compass center to this new dot, and again draw a dot at the location of the compass needle head (or tail). Remove the compass from the paper and draw lines connecting the dots with arrows indicating the direction that the compass points. Repeat steps c-d until the line meets the magnet or paper’s edge. Pick another spot near the magnet and repeat the process (steps a-e).
