Q: A coil of wire is placed in a magnetic field. If the magnetic field strength is doubled, what happens to the induced EMF?

Solution: Doubling the magnetic field strength will double the induced EMF, as it is directly proportional to the magnetic field strength.

Steps: 5

Step 1: Understand that a coil of wire in a magnetic field can have an induced EMF (electromotive force) when the magnetic field changes.
Step 2: Know that the induced EMF is directly related to the strength of the magnetic field.
Step 3: If the magnetic field strength is doubled, it means the strength is increased two times.
Step 4: Since the induced EMF is directly proportional to the magnetic field strength, doubling the magnetic field will also double the induced EMF.
Step 5: Therefore, if the magnetic field strength is doubled, the induced EMF will also be doubled.
