state gov RPSC 2nd Grade Senior Teacher Mock Test Series 2025 Physics Electromagnetic Induction and Inductance Magnetic Flux
The magnetic field in any region is given by \(\overrightarrow B = {B_0}\left( {2 + \frac{x}{a}} \right)k \). A square loop of edge length 'l' is placed with its edge along x and y axis. The loop is moved with a constant velocity \(\overrightarrow v = {v_0}\widehat i\) .
The emf induced in the loop will be-
1
zero
2
v0B0ℓ
3
\({v_0}{B_0}\frac{{{\ell ^2}}}{{a}}\)
4
\({v_0}{B_0}\frac{{{\ell ^2}}}{{2a}}\)
