Questions & Step-by-Step Solutions
If the area of a loop is doubled while the magnetic field remains constant, how does the induced EMF change?
Step 1: Understand that induced EMF (Electromotive Force) is related to the area of the loop in a magnetic field.
Step 2: Remember that if the area of the loop increases, the induced EMF also increases.
Step 3: Note that the problem states the area of the loop is doubled.
Step 4: Since the area is doubled, the induced EMF will also double.
Step 5: Conclude that if the area of the loop is doubled while the magnetic field remains constant, the induced EMF doubles.
Faraday's Law of Electromagnetic Induction – Induced EMF is proportional to the rate of change of magnetic flux, which depends on the area of the loop and the magnetic field strength.
