Question

in 0.600s, the bar moves 1.00 m/ if the magnetic field is 0.0777 T, how much EMF is generated?
(hint: What is the initial and final area of the loop?there is only one loop: N=1.)

Answer 3

help

Answer 4

the emf generated is the rate of change of flux through the area

Answer 5

faraday's law

Answer 6

\( EMF= -n \frac{\Delta (BA)}{\Delta t}\)

Answer 7

it's important to see why the flux is even changing

Answer 8

the magnetic field is constant

Answer 9

but the area of the loop is decreasing bcz the bar is shifting to the left

Answer 10

i like the way how u explain theSmartOne

Answer 11

not this one

Answer 12

the flux through the coils of a solenoid changes from 6.79*10^-4 Wb to 1.33*10^-4 Wb in 0.0333 s. if the solenoid has 605 loops, how much EMF is generated?
(units=Volts)

Answer 13

not this one the one i just sent

Answer 14

btw the current generated by the induced emf would be in the clockwise direction.
It's in the clockwise direction because a clockwise current could generate a magnetic field that goes into the plane.
It does so because the flux is going inwards and the moving rod is reducing this flux by decreasing area.

effect is such as to oppose the cause of
the effect." - Lenz's law
