Web13 jan. 2024 · Figure : (a) Magnetic flux changes as a loop moves into a magnetic field; (b) magnetic flux changes as a loop rotates in a magnetic field. It’s interesting to note that what we perceive as the cause of a particular flux change actually depends on the frame of reference we choose. WebThe flux Φ = BA cos θ is related to induction; any change in Φ induces an emf. All induction, including the examples given so far, arises from some change in magnetic …
