Electromagnetic Induction (11 of 15) Lenz's Law, An Explanation

A circular loop of wire with radius r = 0.0480 m and resistance R = 0.160 Ω is in a region of spatially uniform magnetic field, as shown in Fig. E29.22. The magnetic field is directed out of the plane of the figure. The magnetic field has an initial value of 8.00 T and is decreasing at a rate of dB/dt = -0.680 T/s. <img src="https://lightcat-files.s3.amazonaws.com/problem_images/ab53ddde28219af1-1674070755337.jpg" alt="" /> (a) Is the induced current in the loop clockwise or counterclockwise?

An outer ring is connected to a variable voltage source. If the battery's voltage is continuously INCREASING, what is the direction of the induced current in the inner ring, centered inside of the outer ring?<img class="fr-dii"src="https://static.studychannel.pearsonprd.tech/courses/physics/thumbnails/images/8ce84ff0">

A circular loop of wire is in a region of spatially uniform mag-netic field, as shown in Fig. E29.15. The magnetic field is directed into the plane of the figure. <img src="https://lightcat-files.s3.amazonaws.com/problem_images/59dbb3af80d67dac-1672418250485.jpg" alt="" /> Determine the direction (clockwise or counterclock-wise) of the induced current in the loop when (a) B is increasing; (b) B is decreasing; (c) B is constant with value B_0. Explain your reasoning.
