Question

What happens when changing magnetic flux passes through a coil that is an open circuit with infinite resistance?

Options

• Emf is induced, but no current flows.

• Current flows, but no emf is induced.

• Neither emf nor current can be induced.

• Both emf and current necessarily flow.

Answer 1

Changing magnetic flux still induces emf in an open coil. Because the circuit is open, no current flows.
