No Recording Today
Wednesday 4/21/21
students viewed MIT 8.02 Video Lecture 16 (through 34 ish minutes)
discussed notes associated with video lecture above
discussed how current can be induced in two different ways: (1) change size or orientation of a circuit in a constant B field; (2) change the magnetic field through a stationary circuit
discussed how a conducting rod/wire dragged through a uniform magnetic field sets up an induced electric potential...process of charge separation stops when the magnetic force = electric force or qvB=qE which means vB=E ... discussed that the potential difference induced, V=v(L)(B) where L is the length of the conductor, v is the speed it is dragged through the field, and B is the strength of the field.
worked an example problem of dragging a conductor through an unknown magnetic field (given L, V, and v, determine B's magnitude and direction)
Thursday 4/22/21
discussed the physics of a conductor rotating in a magnetic field
discussed completing the circuit for a conductor being pulled across conducting rails and generating an induced current...discussed how this induced current creates an induced B field that opposes the direction of the original field (Lenz's Law)
discussed magnetic flux in different contexts
revisited the situation of a conductor being pulled across conducting rails in the context of flux change and got the same result for the induced current
Friday 4/23/21
worked several examples involving Faraday's Law
watched MIT 8.02 Lecture Video 20 on Inductance and the RL Circuit (through 30:54)
Monday 4/26/21
livestream
worked several more examples involving Faraday's Law
discussed "charging" and "discharging" for RL Circuit with number examples for each
discussed LC circuit and compared it's math to the math for mass on a spring...did analogy comparisons of LC Circuits and mass/spring circuits
reviewed self-inductance for a loop
viewed as many Sharpie Man videos on section R Inductance as we could watch before the end of class
