Demonstrates how the angle of intersection affects the field density in a given surface area.
Equipment:
1. OHP transparency w/ dots 2. Square metal frame
(Stored in plastic 9” x 12” envelope)
Procedure:
1. Place transparency sheet on OHP. 2. Place wire frame on top of sheet and notice the number of dots inside the frame. 3. Rotate the frame to 45° angle. Notice the change in flux density.
