A rectangular loop of 270 turns is 33cm wide and 17cm high.?

Question

Part A
What is the current in this loop if the maximum torque in a field of 0.49T is 22N⋅m ?
Express your answer using two significant figures.
Answer in A

Answer 1

Number of turns N= 270 turns

Width b =33cm

Height h =17 cm

Magnetic field B=0.49 T

Torque T=22 N-m

Caculate current by using the formula

T=NIABsinθ

  =NIbhBsinθ

  22=(270)(I)(0.33)(0.17)sin90

I =22/(270)(0.33)(0.17)

  =1.45 A

torque (t) = NIABsintheta
