Question

Activity 4: Lenz's Law 20. Is there current flovw induced in the loop ?00pof wire of wire at right? If yes, what direction clockwise or counter-clockwise? Magnetic Field pointing out of the page, Magnitude constant. 21. Is there current flow induced in the loop Loop of wire of wire at right? If yes, what direction, clockwise or counter-clockwise? Magnetic Field pointing into the page, Magnitude constant. 22. Is there current flow induced in the loop Loop of wire of wire at right? If yes, what direction, clockwise or counter-clockwise? Magnetic Field pointing out of the page, Magnitude increasing. 23. Is there current flow induced in the loop of wire at right? If yes, what direction, Loop of wire clockwise or counter-clockwise? Magnetic Field pointing into the page, Magnitude increasing.

Explanation / Answer

20) No

because, there is no change in magnetic flux through the loop.

21) No

because, there is no change in magnetic flux through the loop.

22) Yes. clocwise.

because, the direction of induced current is such as to oppose the change in megnetic flux that generated it.

24) Yes. counterclockwise.
because, the direction of induced current is such as to oppose the change in megnetic flux that generated it.
