Scientific work is currently underway to determine whether weak oscillating magnetic fields can affect human health. for example, one study found that drivers of trains had a higher incidence of blood cancer than other railway workers, possibly due to long exposure to mechanical devices in the train engine cab. consider a magnetic field of magnitude 0.00100 t, oscillating sinusoidally at 61.5 hz. if the diameter of a red blood cell is 7.20 µm, determine the maximum emf that can be generated around the perimeter of a cell in this field.

The maximum emf that can be generated around the perimeter of a cell in this field is

Explanation:

To solve this problem it is necessary to apply the concepts on maximum electromotive force.

For definition we know that

Where,

N= Number of turns of the coil

B = Magnetic field

Angular velocity

A = Cross-sectional Area

Angular velocity according kinematics equations is:

Replacing at the equation our values given we have that

Therefore the maximum emf that can be generated around the perimeter of a cell in this field is

i think it’s a. this is because if they measured the mass of something with a mass of 150g, then their final answer would have to be approximately 150g. though all of their answers are almost 150, rosa and tran have the closest answers (or the exact answer) to the accurate one.
