## A2-22: MAGNETIC VECTORS - LECTURE HALL BLACKBOARDS

• ID Code: A2-22
• Purpose: Demonstration of vector properties
• Description: Various length of magnetic vectors that can be affixed to Lecture Hall boards. The lengths are in the ratio 3:4:5, so that they can form a right triangle. Illustrate vector addition, subtraction, motion of vectors, and commutative properties. Only usable in large lecture halls with steel-backed chalkboards.
