Question
The drawing shows a straight wire carrying a current I. Above the wire is a rectangular loop that contains a resistor R. If the current I is decreasing in time, what is the direction of the induced current through the resistor R — left-to-right or right-to-left? If the induced current goes from left to right through the resistor, type the letters "LTR" in the box below. If the current goes from right to left through the resistor, type the letters "RTL" in the box. Please include units. Thank you!
Explanation / Answer
Current is decreasing with time ,so the magnetic field due to this will also decreases in loop which is having direction into the plane using the right hand palm rule ... Therefore , induced current developed in loop will increase the effect such that the direction should be clockwise ,so that magnetic field shud be inot the plane .... For clockwise , current should be from left to right . Answer is LTR
