... What are three ways to change magnetic flux? <6a> Be able to use Faraday’s law and Lenz’s law to recognize situations in which changing flux through a loop will cause an induced emf or current in the loop. (is it a complete loop? Is the flux changing with time? Resistance?) <5,13,14-16> Be abl ...
