Step 6. Apply RIGHT-HAND-RULE #2 on the INDUCED FIELD to determine the direction of the INDUCED current in the RING. As viewed in the figure, the induced current is directed [Select ] If the current-carrying RING is treated as an equivalent bar magnet, mark its north and south poles. The NORTH pole is at the bottom of the ring, the SOUTH pole is [SouthPole2] Step 7. Look at the equivalent bar magnets in step 3 and step 6 and recall how magnetic poles interact, answer the question: will the ring move toward or away from the coil? toward
Partial Question 2 Lab 4 Electromagnetic Induction Lab Worksheet Problem 5b If the polarities of the battery are reversed, as shown in this figure, predict what will happen. The ring will move [Select] ✰ the coil. Apply the analyses in 5a to this situation to verify your prediction. Problem 5b Iron core Coil Metal ring Switch + 1.5 / 2 pts Battery step 1. With the switch open, what is the direction of the magnetic flux through the ring? [ Select]
Step 2. Mark the direction of the current in the coil after the switch is closed. On this view, the current is directed From left to right Step 3. Draw magnetic field lines through the coil and the RING. Do you apply Right-Hand-Rule #1 or #2? #2 Label this field as the ORIGINAL field. Original Field direction: Upward If the current-carrying coil is treated as an equivalent bar magnet, mark its north and south poles. The NORTH pole is at the bottom of the coil, the SOUTH pole is at the top of the coil. Step 4. From step 1 (switch open) to step 3, how does the magnetic flux through the RING change? increases Step 5. Apply Lenz's Law to determine the direction of the INDUCED magnetic field in the RING. Upward Step 6. Apply RIGHT-HAND-RULE #2 on the INDUCED FIELD to determine the direction of the INDUCED current in the RING. As viewed in the figure, the induced current is directed From right to left If the current-carrying RING is treated as an equivalent bar magnet, mark its north and south poles. The NORTH pole is at the bottom of the ring, the SOUTH pole is at the top of the ring Step 7. Look at the equivalent bar magnets in step 3 and step 6 and recall how magnetic poles interact, answer the question: will the ring move toward or away from the coil? [move]
