Questions & Step-by-Step Solutions
What is the induced EMF in a loop of wire if the magnetic flux through it changes at a rate of dΦ/dt?
Step 1: Understand that EMF stands for electromotive force, which is the voltage generated by a changing magnetic field.
Step 2: Know that magnetic flux (Φ) is a measure of the amount of magnetic field passing through a loop of wire.
Step 3: Recognize that when the magnetic flux changes over time, it induces an EMF in the wire loop.
Step 4: Recall Faraday's law of electromagnetic induction, which states that the induced EMF (ε) is equal to the negative rate of change of magnetic flux.
Step 5: Write the formula for induced EMF: ε = -dΦ/dt, where dΦ/dt is the rate of change of magnetic flux.
