Twelve > Magnetic Field due to a Current

Asked by Atith Adhikari · 2 years ago

A long, straight wire carrying a current of 1.0 A is placed horizontally in a uniform magnetic field B = $\rm 1.0 \times 10^{-5}$ T pointing vertically upward (figure 35-E1). Find the magnitude of the resultant magnetic field at the points P and Q, both situated at a distance of 2.0 cm from the wire in the same horizontal plane.
