Question

Suppose you take a short piece of wire that is not attached to anything and move it up and down in a magnetic field. Explain whether or not a current will be induced, and why

Answer 1

Answer:

A current will not be induced because the wire is not part of a closed circuit. The electrons have no place to flow to.

Explanation:

Answer 2

Answer:

No.

Explanation:

• According to Faraday's law, the induced emf in the circuit is given by :

         $e=\dfrac{d\phi}{dt}$, it is proportional to the rate of change of magnetic flux.

• In this case, a short piece of wire that is not attached to anything and move it up and down in a magnetic field. It means that the circuit is not completed here. It is an open circuit. For the induction of current, a circuit must be completed.
• Hence, no current will induce.
