Question asked by Filo student

Q4)A structure formed from two straight conducting rods forming a right angle, is placed in a uniform magnetic field with $B=0.40\mathrm{T}$ is directed out of the page. A straight conducting bar in contact with the structure, starts at the vertex at time $\mathrm{t}=0$ and moves with a constant velocity of $5.0\mathrm{m}/\mathrm{s}$ along them. Calculate the emf around the triangle at that time $\mathrm{t}=4.0\mathrm{s}$.

1. $80\mathrm{V}$
2. $40\mathrm{V}\mathrm{V}=5\mathrm{m}/\mathrm{s}$
3. $20\mathrm{v}t=4\mathrm{s}$
4. 0
