Answer 1

$\sf{\red{Let's \:assume}}$

• ★ Metallic Length of rod is = L
• ★ Magnetic field = ẞ
• ★ External length = DX
• ★ Distance = x
• ★ linear velocity = v

⠀⠀⠀

⠀⠀⠀

$\sf{\red{Solution}}$

$\boxed{\text{Area swept by dx=vdxdt}}$

➥De = ß $\frac{Da}{Dt}$=Bvdx

➥But v=xω

➥dE=Bxωdx

➥E=∫o¹Bxωdx

➥Bω = $\frac{l²}{2}$

Answer 2

Answer:

Let

′

sassume

★ Metallic Length of rod is = L

★ Magnetic field = ẞ

★ External length = DX

★ Distance = x

★ linear velocity = v

⠀⠀⠀

\sf{\red{Solution}}Solution

\boxed{\text{Area swept by dx=vdxdt}}

Area swept by dx=vdxdt

➥De = ß \frac{Da}{Dt}

Dt

Da

=Bvdx

➥But v=xω

➥dE=Bxωdx

➥E=∫o¹Bxωdx

➥Bω = \frac{l²}{2}
