(D) direct current of varying emf is generated

Answer 1

✦alternating EMF of varying frequency is generated✌❤❤✌✌✌❕❕

Answer 2

⭐《ANSWER》

$\huge\mathfrak\pink {ANSWER}$

↪Actually welcome to the concept of the ELECTROMAGNETIC INDUCTION

↪Baiscally , we know that ,

↪According to the SIR MICHEAL FARADAY'S LAW of ELECTROMAGNETIC INDUCTION

↪The Rate of Change of the MAGNETIC FLUX LEADS to the Production of the INDUCED EMF

↪Now here, MAGNETIC FLUX refers as the NUMBER OF MAGNETIC FIELDS LINES PASSING Through a Closed Surface

↪Now it is Mathematically given as

〽Phi ( ⊙) = B.A. COS ○

↪since here none of the criteria is changing , and also the magnetic induction field is Uniform , thus we can say that ,

↪ALTERNATING EMF OF CONSTANT MAGNITUDE IS GENERATED
