A loop of wire is moved into a magnetic field at a constant speed. What happens

₹0.0

Question: A loop of wire is moved into a magnetic field at a constant speed. What happens to the induced EMF as the loop enters the field?

Options:

Correct Answer: Induced EMF increases

Solution:

As the loop enters the magnetic field, the magnetic flux through the loop increases, leading to an increase in induced EMF.

A loop of wire is moved into a magnetic field at a constant speed. What happens to the induced EMF as the loop enters the field?

Step 1: Understand that a loop of wire can generate electricity when it moves through a magnetic field.
Step 2: Recognize that a magnetic field is an area where magnetic forces are present.
Step 3: When the loop of wire starts to enter the magnetic field, it begins to experience magnetic forces.
Step 4: As the loop moves further into the magnetic field, the amount of magnetic field lines passing through the loop increases.
Step 5: This increase in magnetic field lines is called an increase in magnetic flux.
Step 6: According to Faraday's Law of Electromagnetic Induction, an increase in magnetic flux through the loop induces an electromotive force (EMF).
Step 7: Therefore, as the loop enters the magnetic field, the induced EMF increases.

Electromagnetic Induction – The process by which a changing magnetic field within a closed loop induces an electromotive force (EMF) in the wire.
Magnetic Flux – The product of the magnetic field strength and the area of the loop through which the field lines pass, which changes as the loop enters the magnetic field.
Faraday's Law of Induction – The principle stating that the induced EMF in a circuit is directly proportional to the rate of change of magnetic flux through the circuit.
