Given :
Magnitude of current flowing in the wire = 8A
Magnitude of the positive charged particle = 7C
Distance of the wire = 0.05 m
Velocity of the charged particle = 250 m/s
To Find :
The magnetic field due to the flow of current in the wire
Solution :
- Magnetic field due to the current carrying wire is given by
- By substituting the values in the above equation
The magnetic field due to the flow of current in the wire is 3.2×10⁻⁵ T.
