Answer 2

Answer:

The change in the magnetic flux governs the direction of EMF.

Explanation:

• Lenz's law specifies how current and emf flow.
• According to Lenz's law, an induced electromotive force with a different polarity causes a current whose magnetic field opposes the change in magnetic flux across the loop, ensuring that the loop's initial magnetic flux is preserved.
• One key element that affects the direction of the induced emf is the change in the magnetic flux associated with it.

So, the change in the magnetic flux governs the direction of EMF.
