PhysicsEasysingle choice

A small, metal wire loop is dragged across the gap between the poles of a magnet in $0.4 s$ . If the change in magnetic flux for the wire is $8 \times 10^{- 4} Wb$ , then the emf induced in the wire is

Options:

Answer:

Solution:

$|e| = \frac{dϕ}{dt}$

$= \frac{8 \times 10^{- 4}}{0.4} = 2 \times 10^{- 3} V$
