I need solve this questions

[15 points] Two circular coils, separated by a distance d = 1.1 [m], are located as shown in the gure {image not to scale). I Coil- 1 of 90 ' T | I | | | A d | | I I I l D loops has a radius R1 = 1.4 [m]. A current I. = 2 [A] is owing counterclockwise in the loop. . Coil-2 of 80 loops has a radius R2 = 0.86 [m]. The current I2 is of unknown direction and magnitude. a. [3 Points] Find the magnitude of the magnetic eld at point A due to the current in coil-l. BI =Em h. [2 Points] What is the direction of the magnetic eld at point A due to the current in coil-1? E c. [2 Points] What should be the direction of the current 12 (as seen from above) in coil-2 to have a zero net magnetic eld at point A? E d. [4 Points] Find the value of the current I2. 1: =C1w e. E4 Points] Find the magnitude of the magnetic eld of each coil at its own center. 31::\"11 32 =:]m
