Question 1
What is the statement of Faraday's First Law?
- A change in electric current induces magnetic flux.
- A change in magnetic flux induces an electromotive force (emf).
- An electric circuit creates magnetic flux.
💡 Hint: Remember what induces the emf.
Question 2
Lenz’s Law indicates that induced current will...

Question 1
A coil of length 2 m is moving continuously at 3 m/s through a magnetic field of strength 0.5 T at an angle of 30 degrees. Calculate the induced emf.
💡 Hint: Break it down into components, and don't forget to compute sine of the angle!
Question 2
Explain how increasing the speed of a rotating coil in a generator affects the resulting voltage output. Include concepts of magnetic flux and induced emf in your explanation.
💡 Hint: Link the speed of rotation to rate of magnetic flux change.
