Answer:
The current flows through the rod is 14.9 A.
Explanation:
Given that,
Magnetic field = 0.045 T
Mass of aluminum rod = 0.19 kg
Length = 1.6 m
Angle = 30.0°
We need to calculate the force
Using resolving force
Put the value into the formula
We need to calculate the current flows through the rod
Using formula of magnetic force
Put the value into the formula
Hence, The current flows through the rod is 14.9 A.
