Quick questions on Electromagnetic induction: Faraday's and Lenz's laws - WJEC A-Level Physics
3short Q&A pairs drawn directly from our worked dot-point answer. For full context and worked exam questions, read the parent dot-point page.
What is faraday's law?Show answer
Faraday's law states that the magnitude of the induced EMF equals the rate of change of flux linkage. A faster change of flux (a stronger field, larger area or quicker movement) induces a larger EMF.
What is q1?Show answer
A coil of turns has the flux through it change from to in . Find the average induced EMF. [3 marks]
What is q2?Show answer
State Lenz's law and the conservation principle it expresses. [2 marks]
