NAME PAGE 4 PHYSICS EXPERIMENT 37-1 ELBCTROMAGNITIC INDUCTION -LENZS LAW SECTION 4 what are the results of moving the solenold with the magnet stationary? 5. what do you assume is the relative magnetic field strength of two bar magnets, with like poles held together, compared to a single magnet? 6 How is the maximm current magnitude effected by increasing the magn- tic field strength? 7·How is the maximum current magnitude effected by increasing the num- ber of turns of wire on the col1? PART II Induction Using Primary and Secondary Cotls 8. what conditions in the primary ctrcuit result in the induction of current in the secondary circuit? 9. What is the maximum constant current in the primary circut?A 10. Is current induced in the secondary cotl when there is a constant current in the primary circutt?N M 11. What is the current in the primary before the switch is closed? 12. How does the current in the primary coll change just after the switch is closed? 13. What do you assume happens to the magnetic field of the primary coll just after the switch is closed? 14 Describe the changes that occur in the primary circutt when the switch is opened 15. What is the effect of reversing the direction of the current in the prima circult on the direction of the Induced current in the secondary circult?Explanation / Answer
4. As per the phenomenon of Electromagnetic induction, moving solenoid and stationary magnet gives same effect as stationary solenoid and moving magnet.
Due to motion, the of rate of change of electric flux induces emf across the terminals of solenoid hence a current started to flow acorss it.
Comment in case any doubt.
According to Chegg guidelines we can solve one problem at a time so plz reattach your other problems separately ...Goodluck
