How does electromagnetic induction in a moving loop of wire cause an electric generator to produce an electric current?
A. Mechanical energy flows out of the magnets and into the electric
charges in the loop of wire.
B. Charged particles flow within the wire because they are pushed by
the magnetic field of the magnets.
C. Charged particles flow when the loop of wire is attracted by the
magnetic field of the magnets.
O D. Electrons flow from the magnets into the loop of wire and
continue to flow within the wire.

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
