True or false: in a current, electrons will always flow from negative to positive.
-false. electrons flow from positive to negative because like charges are attracted to each other.
-true. electrons flow from positive to negative because like charges are attracted to each other
-false. electrons do not move
-true. electrons flow from negative toward positive to negative toward positive because opposite charges attract to each other

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.
