Reading of the galvanometer linked to the coil.
Answer to Problem 1OQ
Solution:
E. current spikes as the magnet enters the coil, then a current sparks in the opposite direction as the magnet exits the coil.
Explanation of Solution
when the bar magnet is inserted down into the coil of wire, magnetic flux linked with the changes, an induced EMF and hence the induced current is set up in it.
When the bar magnet is left in the coil for one minute, there will be no change in flux linked with the coil, so no induced current would be produced.
When the bar magnet come out of the coil again, magnetic flux linked with the coil changes, an induced EMF and hence, an induced current is set up in the coil in the opposite direction.
Conclusion: Whenever the magnetic flux linked with a closed-circuit change, an induced EMF and hence, an induced current is set up in it.

- Show that the units 1 v2/Q = 1 W, as implied by the equation P = V²/R. Starting with the equation P = V²/R, we can get an expression for a watt in terms of voltage and resistance. The units for voltage, V, are equivalent to [? v2 v2 A, are equivalent to J/C ✓ X . Therefore, 1 = 1 = 1 A V1 J/s Ω V-A X = 1 W. . The units for resistance, Q, are equivalent to ?
