Hey
Good question
How can we know if I planet was once inhabited by life? There diferent tequnecs for this. The first would be searching in the soil for fossilized microbes. in June of 19, 1976 Viking 1 was launched on its way to mars to began the search of life els wear. What this little lab did was drill a hole in the marsion terrain and take a sample of its soil to search for microbes or microbe fosles. Sadly it did not find anything. Other technics are to search for ruins on the planet or exoplanet. I do not have much to say about this method because it has never been used.
Hope it helped (i wrote all that).

Below is a picture of Carl Sagan next to the Viking Voyager 1. Obveosly this is just a modal. you could not breathe on mars.
Answer:
B = 0.135T
Explanation:
To find the magnitude of the magnetic field you use the following formula, for the torque produced by a magnetic field B in a loop:
(1)
τ: torque = 1.51*10^-5 Nm
I: current = 2.47mA = 2.47*10^-3 A
B: magnitude of the magnetic field
A: area of the loop = 4.97cm^2 = 4.97(10^-2m)^2=4.97*10^-4m^2
N: turns = 181
θ: angle between B and the magnetic dipole (same as the direction of the normal to the plane)
You replace the values of the parameters in (1). Furthermore you do B the subject of the formula:
