Q1
A circular loop of wire is placed in a uniform magnetic field. If the magnetic field is increased, what happens to the induced EMF in the loop?
Increases
Decreases
Remains constant
Becomes zero
According to Faraday's law of electromagnetic induction, an increase in magnetic field through the loop induces an EMF in the loop.

Q
Q: A circular loop of wire is placed in a uniform magnetic field. If the magnetic field is increased, what happens to the induced EMF in the loop?
Solution: According to Faraday's law of electromagnetic induction, an increase in magnetic field through the loop induces an EMF in the loop.
Steps: 5
Step 1: Understand that a circular loop of wire is placed in a magnetic field.
Step 2: Know that a magnetic field is a region where magnetic forces can be felt.
Step 3: Learn about Faraday's law of electromagnetic induction, which states that a change in magnetic field can induce an electromotive force (EMF) in a loop.
Step 4: Recognize that if the magnetic field strength increases, it means there is a change happening in the magnetic field.
Step 5: Conclude that this change (increase) in the magnetic field will induce an EMF in the loop.
