I was hoping to avoid having to use arctan if at all possible...I'm having more luck with the small triangles method in polar coordinates. You take a triangle with height along the x axis, "r". The angle from the x-axis is assumed to be very small, d\theta. Because this is very small, the...

Homework Statement Graph I(1) and I(2) vs. time. See attachment for illustration. Homework Equations V = IR Back EMF = -L * dI/dt The Attempt at a Solution I realize that an inductor is essentially the opposite of a capacitor when it comes to current and voltage: that is, the...

Well, as the field begins to rotate, I believe the flux will decrease as the field becomes more parallel with the loop. Thus, the induced field must increase to augment the field and oppose the change in flux, which means the field going into the page will be strengthened, and right hand rule...

Homework Statement Draw a circle centered on the origin with radius 2. Draw the vertical line x = 1. Find the area bounded on the left by x=1 and on the right by the circle. Homework Equations Area of a circle: x^{2} + y^{2} = r^{2}. In this race, r = 2 Polar coordinates: x =...

Homework Statement Using Faraday's law, state the direction of current in the loop on the left. (Picture attached) Homework Equations \epsilon = -d\Phi/dt The Attempt at a Solution I know that, assuming the direction of the current on the right side of the loop is from positive...
