5K10.20 - Faraday's Laws - Induced Currents

Code Number:
5K10.20
Demo Title:
Faraday's Laws - Induced Currents
Condition:
Excellent
Principle:
Currents and Forces by Induction
Area of Study:
Electricity & Magnetism
Equipment:
Lecture Table Galvanometer, Large and Small Coils, Horn and Bar Magnets, and Spring and Iron Masses.
Procedure:

Video Credit: Jonathan M. Sullivan-Wood

See 7F10.35.

Connect the galvanometer to one of the coils. Hold the coil still and move the magnet through the coil and observe the galvanometer deflection. Hold the magnet still and move the coil and again observe the deflection. Observe the effect when different poles of the magnet are used.

Simple Harmonic Motion or alternating current may be demonstrated by hanging some iron masses on a spring and sticking a magnet onto the bottom of the mass. Place the coil around the magnets when they are oscillating. The output of the coil can be shown on either the galvanometer or the oscilloscope.
