... (to the right) at 900 to the 4 km and make it exactly 6cm long (1 km ≙ 2 cm; 3km ≙ 6cm). At the end of this line (at 6 cm) you have found the exact position of B. You now join A to B and measure the length of AB. You will find it to be 10 cm long. Now you use the scale in reverse. For every 2 cm you ...

Chapter 29: Magnetic Fields
... An important difference between electric charges and magnetic poles is that poles are ALWAYS found in pairs (N,S) while single electric charges (positive or negative) can be isolated. For example, if you cut a bar magnet in half each piece will have a N and S pole! 2) The forces between magnets are ...
