Question

According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. True False

Answer 1

Answer:

True.

Explanation:

According to Lenz's law, the induced current in a circuit always flows to oppose the external magnetic field through the circuit. This statement is true.

The Faraday's law of induction is given by :

$\epsilon=-\dfrac{d\phi}{dt}$

Here, negative sign shows that the direction of induced emf is such that opposes the changing current that is its cause.

Hence, the statement is true.
