Magnetic resonance imaging requires a magnetic field of about 1.5 t in the center of a current-carrying circular coil having n loops. if the radius of a single loop is a = 0.25 m, the total magnetic dipole moment μ associated with the coil is: a) 1.17 x 10^5 a . m^2 (b) 5.27 x 10^4 a . m^2 (c) 8.17 ×10^3 a . m^2

yup its correct its: c) b b

it is given that trillions of microbes make up to 1% to 3% of the body mass.

let's take average of this percentage: 2%

consider the average mass of the human body as 70 kg.

then, trillions of microbes would have mass  

therefore, 100 trillion micro-organisms would weigh:

this is an approximate value and could change depending on the mass of the human body and percentage of the microbes present in it.

average mass per microorganism =
