$P$ and $Q$ are two circular thin coils of same radius and subjected to the same rate of change of flux. If coil $P$ is made up of copper and $Q$ is made up of iron, then the wrong statement is

Options:

Answer:

Solution:

Induced emf is,

$[∵ e = - \frac{d φ}{d t} = - A \frac{d B}{d t}]$

Therefore induced emf and direction of current does not depend on material of the coil but resistance of copper is less than iron therefore current in copper coil is more.
