Activity 5: Rope Mazes Form groups of 2-3 children, each with their own skipping rope and a few cones. Using their ropes and cones, each group makes a maze on the floor that involves a hopping and jumping challenge. Once all groups have finished, children circulate to other groups to try the different mazes.
The electric field strength is inversely related to the square of the distance. So by whatever factor d changes by, the E value is altered in the inverse direction by the square of that factor. The specifics are as follows: a) d increases by a factor of 2; divide the original E by 4.
When the field lines are close together, the magnetic field is strong. When the field lines are far away from one another, the magnetic field is weak. A unit of measure of the strength of the magnetic field is the Gauss or the Tesla. So, let's look at some field lines and magnetic fields around various magnets. For these diagrams, I used a small arrow inside the magnet to show the direction of the magnetic field lines. The head of the arrow would be pointing to the North pole of the magnet and away from the South pole of the magnet. Bar Magnet.
