[-/1 Points] DETAILS OSUNIPHYS1 30.4.P.047. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Calculate the induced electric field (in V/m) in a 52-turn coil with a d netic field of magnitude 0.70 T so that the face of the coil and the magnetic field are perpendicular. This magnetic field is reduced to zero in 0.10 seconds. Assume that the magnetic field is cylindrically symmetric with respect to the central axis of the coil. (Enter the magnitude.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER The current in a long solenoid of radius 2 cm and 18 turns/cm is varied with time at a rate of 8 A/s. A circular loop of wire of radius 4 cm and resistance 3 0 surrounds the solenoid. Find the electrical current induced in the loop (in HA). HA Additional Materials Reading Submit Answer 16. [-/4 Points] DETAILS OSUNIPHYS1 30.4.WA.030. TUTORIAL. MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Assume in the figure below the positive z direction points out of the page and the negative z direction points into the page. In the circular region of radius R = 25.0 cm in the figure below, there is a magnetic field that is dire to and out of the page. The magnetic field is given by the equation B, = a - bt in the circular region. Outside of this circular region, the magnetic field is always zero. Here a = 15.0 T and b = 1.13 T/52 . (a) At t = 0.350 s, find the magnitude and direction of the electric field at the location A, where dj = 12.0 cm.

MY NOTES ASK YOUR TEACHER PRACTICE ANOTHER Design a current loop that, when rotated in a uniform magnetic field of strength 0.73 T, will produce an emf & = 8, sin(wt), where &. = 110 V and w = 1207 rad/s. First, choose the number of turns the loop should have. (Enter a positive integer less than 100.) turns Then calculate the needed area of the loop (in m2). (Use the number of turns you entered above.) 7m2 Additional Materials Reading
