besides, the unit of a magnetic field is tesla (t). magnetic field magnitude = \(\frac{(permeability of free space) (current magnitude)}{2\pi (distance)}\) b = \(\frac{\mu_{0}}{2\pi r}\) derivation of the formula. b = refers to the magnetic field magnitude in tesla (t) \(\mu_{0}\) = refers to the permeability of free space (\(4\pi \times 10^{-7} t \cdot m/a\))
step-3: by multiplying gear-ratio between 1 to 2 and 2 to 3. we will get resultant gr between driver and driven gear. resultant multi gear train gr = 0. 5 0.5 = 0.25. from the above, calculated gear ratio we can calculate the speed and torque at output gear.

the speed of light in a vacuum is defined in the si system to be 299,792,458 m/s (about a billion km/h). this is usually stated with a more reasonable precision as 3.00 10 8 m/s. the speed of light in a vacuum is assigned the symbol c (italic) when used in an equation and c (roman) when used as a unit.
when two bodies move in opposite direction, then the relative speed = sum of speeds i.e for e.g. for a person sitting in a train moving with a speed of 40 km/hr in the west direction, another train which is going towards east with a speed of 40 km/hr, will appear to move at a speed of (40+40) = 80 km/hr.
