assignment=30279548&mode-; 1 e 1 a Search Answer in units of T. 017 (part 1 of 2) 10.0 points A circular coil of 593 turns and area 0.84 m is in a uniform magnetic field of 0.49 T. The maximum torque exerted on the coil by the field is 0.0071 N·m. Calculate the current in the coil. Answer in units of A. 018 (part 2 of 2) 10.0 points Assume the 593 turns of wire are used to form a single-turn coil with the same shape but much larger area. What is the current if the maximum torque exerted on the coil by the field is 0.0071 N·m? Answer in units of A 019 (part 1 of 3) 10.0 points Consider a reetangular eurreut loop lving in

Explanation / Answer

torque acting on a wire is T = N I A B

where N is no. of turns = 1

B is amgnetic field = 0.49 T

Area A = 0.84 m^2

so

Current I = T/( N A B)

I = (0.0071/(593* 0.84 * 0.49)

I = 29 uA

----------------------------------

# 18:

one turn has a length 2pi R = 593

Raidus = 593/(2pi)

R = 94.37 m

so Area A = pi r^2 = 3.14 * 94.37 * 94.37

A = 27963.88 m^2

so Current I = (0.0071)/(1 * 27963.88 * 0.49)

I = 0.518*10^-7 A (ANSWER)
