Question

Twelve wires of equal length are connected in the form of a skeleton cube, which is moving with a velocity V in the direction of magnetic field B. Find the emf in each case.

Answer 1

Answer:

Explanation:

e = -dΦ/dt = -d(B.A)/dt

So the emf will be induced when the flux enclosed will be changing with time.

In this case neither the area of any face of the cube nor the magnetic field is changing, hence no emf is induced.

Answer 2

$\huge\textbf{Heya}$
$<b>$
✔️e = -dΦ/dt = -d(B.A)/dt✔️
▲So the emf will be induced when the flux enclosed will be changing with time.
▲In this case neither the area of any face of the cube nor the magnetic field is changing
Therefore,no emf is induced.
