- What is the direction of the induced current in resistor A when coil B is moves to the left and then stops moving? there is no current O from left to right O form right to leftCAN YOU HELP WITH 4A AND SUBQUESTION 4B PLEASE 4a. Suppose a 42–turn coil lies in the plane of the page in a uniform magnetic field that is directed into the page. The coil originally has an area of 0.290 m2. It is stretched to have no area in 0.100 s. What is the magnitude of the induced emf if the uniform magnetic field has a strength of 1.70 T? 4b. What is the direction of induced emf? A. CCW B. CW THIS IS NOT AND WILL NOT BE GRADEDIn a well-designed transformer with an iron core, the secondary coil has twice as many turns as the primary coil. Which one of the followi statements concerning this transformer is true? OA This is a step-down transformer because the current in the secondary coil is less than that in the primary coll. OB The effect of the iron core is to reduce the magnetic field passing through the coils. C The induced emf generated in the secondary coil is twice as large as that generated in the primary coil. 9:44 PM O D. The flux that passes through each turn of the primary coil is twice the flux that passes through the secondary coil.
