It is maximum
It is minimum
It is zero
It fluctuates
When a magnetic field is applied perpendicular to a loop of wire, the magnetic flux through the loop is maximized, resulting in maximum induced EMF according to Faraday's law.

Q
Q: If a magnetic field is applied perpendicular to a loop of wire, what is the effect on the induced EMF?
Solution: When a magnetic field is applied perpendicular to a loop of wire, the magnetic flux through the loop is maximized, resulting in maximum induced EMF according to Faraday's law.
Steps: 7
Step 1: Understand what a magnetic field is. It is an invisible field that exerts a force on charged particles and magnetic materials.
Step 2: Know what a loop of wire is. It is a closed circular path made of conductive material through which electric current can flow.
Step 3: Learn about magnetic flux. It is the amount of magnetic field passing through a surface, like our loop of wire.
Step 4: Recognize that when a magnetic field is applied perpendicular to the loop, it means the field is directly entering or exiting the loop.
Step 5: Realize that this perpendicular position maximizes the magnetic flux through the loop because the entire area of the loop is exposed to the magnetic field.
Step 6: Understand Faraday's law of electromagnetic induction, which states that a change in magnetic flux through a loop induces an electromotive force (EMF) in the loop.
Step 7: Conclude that since the magnetic flux is maximized when the field is perpendicular, the induced EMF will also be at its maximum.
