Questions & Step-by-Step Solutions
What is the effect of increasing the number of turns in a coil on the induced EMF when the magnetic field changes?
Step 1: Understand what a coil is. A coil is a wire wound in a spiral shape.
Step 2: Learn about magnetic fields. A magnetic field is an area around a magnet where magnetic forces can be felt.
Step 3: Know what EMF (Electromotive Force) is. EMF is the voltage generated by a coil when the magnetic field changes.
Step 4: Familiarize yourself with Faraday's law. It states that the induced EMF in a coil is related to how quickly the magnetic field changes and how many turns the coil has.
Step 5: Realize that more turns in the coil means more wire is present to interact with the changing magnetic field.
Step 6: Conclude that if you increase the number of turns in the coil, the induced EMF will also increase when the magnetic field changes.
