Document Summary

Example 1c: what is the magnetic flux in the loop below, bacos(theta) as b and plane of a have to be perpendicular. Question 2: consider square loop with total area a and a magnetic field of strength b occupying space as shown. What is the total magnetic flux through the loop: 0 (now there is magnetic field on both sides but flux cancel out b*a/2 - b*a/2) Faraday"s law of induction: magnitude of induced emf, the rate of change of magnetic flux through closed circuit induces an emf in the circuit o o. Sign is super important as it indicates the direction of induced emf. Physics 102 (provatas) - t/r 11:35-12:55 o: closed loop and flux going through it are analyzed o, 1) the b-field (change in b over change in time) Induced emf caused by changes in flux in any of the following ways. Take magnetic field given perpendicular to the plane of the hoop.
