As a dilligent physics student, you carry out physics experiments at every opportunity. At this opportunity, you carry a 1.11-m-long rod as you jog at 3.07 m/s, holding the rod perpendicular to your direction of motion. What is the strength of the magnetic field that is perpendicular to both the rod and your direction of motion and that induces an EMF of 0.287 mV across the rod

The strength of the magnetic field is 0.0842 mT

Explanation:

Given:

Velocity of rod

Length of rod m

Induced emf across the rod V

According to the faraday's law

We have a special case for moving rod in magnetic field.

Induced emf in moving rod is given by,

Where strength of magnetic field

  T

  mT

Therefore, the strength of the magnetic field is 0.0842 mT

hi there!

out of the two, (b) precision would be more reasonable.   however, both a and b could be pretty reasonable.
