Question

Hi there,

Can you please check the following? Please check to make sure its correct and all work is shown. I want to receive full pts. if not correct please show all work clearly.

thanks

4. (30 pts) a) (10 pts) A 12 turn coil encloses an elliptical area having a major axis of 50 cm and a minor axis of 30 cm. The coil lies in the plane of the page. The wire making up the coil carries a current of 6 A in a clockwise direction. If the coil is in a uniform magnetic field of 2 x 10-4 T directed parallel to the page and to the left, what is the magnitude of the torque exerted on the coil? b) (20 pts) Determine and indicate the direction of the acceleration resulting from the magnetic force acting on the particles moving through magnetic fields as shown in each figure below. B at 45° B up 00 B in Bleft C) X X X X X X X X х X х х х

Answer 1

410 Torgue = mxß =NI (A x B) - NJ AB Sinha CA Area of the ellipse - Tab N = No. of twens. B= magnetic field deursity, I= current in the coil. >El = 12 X 6AX 3.141 x(25 X10 15²m) x (95810m) x 2x104T b). Magenetic force on charge a moring field B is in magnetic with speed ve G = e. ЭХ ☺ B = Bolet) e = vo In re (voj x Bo ( 24 ) =a Fimla TELE
Direction of acceleration will be in the same direction as magnetic force
