Question 1
What is the equation for calculating the induced EMF when a conductor moves through a magnetic field?
- ε = B · l · v · sin(θ)
- ε = B · v · θ
- ε = l · v · θ
💡 Hint: Look for the equation we discussed in class.
Question 2
True or False: The angle θ in the motional EMF equation only affects the direction of the induced current, not its magnitude.
- True
- False
💡 Hint: Think about how angles relate to sine values.

Question 1
A conductor of length 1.5 m moves with a velocity of 4 m/s in a magnetic field of strength 0.8 T at θ = 30°. Calculate the induced EMF.
💡 Hint: Remember to convert the angle to sine.
Question 2
If the same conductor is rotated so that it moves perpendicular to the magnetic field lines, what will the induced EMF be?
💡 Hint: Think about the change in angle and how it affects the sine value.
