A square stationary loop is immersed in a magnetic field pointing into the page. The square has side lengths d = 1 cm. The magnitude of the B-field is shown as a function of time in the graph below.
A) Sketch the magnitude of the flux through the loop as a function of time on the graph below. Make sure to put a scale on the y-axis and show all of your work.
B) Sketch the magnitude of the current in the wire as a function of time on the graph below. Assume the resistance of the wire loop is 1 ?. Make sure to put a scale on the y-axis and show all of your work.
C) If another uniform magnetic field were introduced at t = 0.5 s pointing from left to right, as shown below, would this have any effect on the loop? If so, what would happen to it?
A transverse wave on a string is described by the equation y(x, t) = (2.30 cm) sin[(100 rad/s)t + (18 rad/s)x]. How fast does the wave move along the string
