- Connect a 9V battery ( or power supply) to copper wire coils to create a horseshoe magnet. Vary current to vary strength of magnetic force.
- Strength of force can be measured using plate with hook (shown above), and spring force scale (L02, section A-1).
- Located in L01, section
- Purpose: Illustrate principles of electro-magnetic induction.
- Send current through solenoid and measure direction of B-field
using B-field indicator (magnaprobe). Place coil of wire in front of solenoid
and quickly adjust current; galvanometer will indicate induced emf consistent
with Lenz’s law.
