Starting with the equation for newtons second law of motion:
Answer:
The strength of the magnetic field is 0.08 mT
Explanation:
Given:
Length of rod m
Velocity of rod
Induced emf V
According to the faraday's law
We know that the induced emf of rod is given by,
Where magnetic field
For finding the magnetic field,
mT
Therefore, the strength of the magnetic field is 0.08 mT
