Which law states that the induced electromotive force (emf) in a closed loop is equal to the negative rate of change of magnetic flux through the loop? (2022)
Step 1: Understand what induced electromotive force (emf) means. It is the voltage generated by changing magnetic fields.
Step 2: Learn about magnetic flux. It is the measure of the amount of magnetic field passing through a surface.
Step 3: Know that a closed loop refers to a complete circuit where current can flow.
Step 4: Recognize that Faraday's Law describes the relationship between changing magnetic fields and induced emf.
Step 5: Remember that Faraday's Law states that the induced emf is equal to the negative rate of change of magnetic flux through the loop.
