Title: Oersted's Effect
PIRA: 5H 10.20

Demonstrates: Deflection of a compass needle near a current carrying wire.
Description: Oersted observed that a compass needle placed near a wire deflected when current flowed. In this demo, a long compass needle deflects one way when current flows in a nearby wire. When the direction of current is reversed, a different deflection is seen.

Instructions:

Items Used: Power supply, Oersted apparatus, banana cables

Notes: Less current causes less deflection. Multiple needles available. Needles take time to stop motion once current is applied. Math Description: None.

Size: 9 Condition: Good. Hazard: None.

Schematic: None. Tech Specs: None. Web Links:
