I. MATERIAL Using your computer, tablet or phone and navigate to: https://phet.colorado.edu/sims/cheerpj/faraday/latest/faraday.html?simulation=faraday

II. PROCEDURE 1. Using the Phet simulation choose the "Pick-up coil", you may use controls like, flip polarity, change indicator to bulb or voltmeter, show field and compass and change the number of loops (1-3). 2. Insert the magnet into the coil. Let the bar magnet stay at rest inside the coil. Observe. 3. Pull the bar magnet out. Insert it again into the coil. Observe the direction of motion of the needle of voltmeter. 4. Repeat the step but move the magnet in and out of the coil of wire faster. Observe the deflection of the needle of voltmeter or you may use the bulb. 5. Hold the magnet steadily. This time move the coil of wire quickly towards and away from the magnet. Observe the voltmeter/bulb. 6. Do it again, altering the number of turns, loop area and flip the polarity of the magnet.

Guide Questions 1. What happens to the bulb/voltmeter when the bar magnet is placed closer to the coil of wire? _____________________________________________________________________________________ 2. What does it indicate? _____________________________________________________________________________________ 3. When the magnet is placed stationary at the coil of wire, what happens to the bulb/voltmeter? _____________________________________________________________________________________ 4. What is the direction of the voltmeter needle when the magnet is inserted into the coil? When the magnet is pulled out of the coil? What if you flip the polarity of the magnet? _____________________________________________________________________________________ 5. Does the magnetic field change faster or slower when the magnet is inserted into or pulled out from the coil of wire continuously? _____________________________________________________________________________________
