A vertical wire kept in `Z-X` plane carries a current from `Q` to `P` (see figure). The magnetic field due to current will have the direction at the origin `O` along

The magnetic field at the origin due to the current flowing in the wire is

The magnetic field at the origin due to the current flowing in the wire is

The magnetic field at the origin due to the current flowing in the wire is

A vertical wire carriers a current upwards. The magnetic field at a point due north of the wire is directed

A long, straight wire lies along the y-axis and carries a current I=8A in the y-direction (as shown in Fig) In addition to the magnetic field due to the current in the wire, a uniform magnetic field vecB_0 with magnitude 1.50xx10^-6T is in the +x direction. What is the total field (magnitude and direction ) at following points in the plane? (a) x=0,z=1.00m (b) x=1.00m,z=0 (c) x=0, z=-0.25m

Find magnetic field at O due to the current carrying conductor as shown in the figure.
