**(a)** False

Induced emf/Fraday's law:

$\overline{){\mathbf{\epsilon}}{\mathbf{=}}{\mathbf{-}}\frac{\mathbf{d}{\mathbf{\varphi}}_{\mathbf{B}}}{\mathbf{d}\mathbf{t}}}$

The induced emf is proportional to the **change** in magnetic flux. It does **not** depend on the magnitude of magnetic flux.

(a) The induced emf in a circuit is proportional to the magnetic flux through the circuit.

true or false

(b) There can be an induced emf at an instant when the flux through the circuit is zero.

true or false

(c) Lenz's law is related to the conservation of energy.

true or false

(d) The inductance of a solenoid is proportional to the rate of change of the current in it.

true or false
