Q
Q: A coil of wire is placed in a changing magnetic field. What phenomenon is observed?
Solution:
According to Faraday's law of electromagnetic induction, a changing magnetic field induces an electromotive force (EMF) in the coil.
Steps: 6
Show Steps
Step 1: Understand that a coil of wire is a loop or series of loops made of conductive material.
Step 2: Recognize that a magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Learn that a changing magnetic field means the strength or direction of the magnetic field is changing over time.
Step 4: Know that when the magnetic field around the coil changes, it affects the electrons in the wire.
Step 5: According to Faraday's law, this change in the magnetic field creates an electromotive force (EMF) in the coil.
Step 6: The induced EMF can cause an electric current to flow in the coil if the circuit is closed.
