A long straight horizontal cable carries a current of `3*3A` in the direction `10^@` south of west to `10^@` north of east. The magnetic meridian of the plane happens to be `10^@` west of the geographic meridian. The earth's magnetic field at the location is `0*33G` and the angle of dip is zero degree. Locate the positions of neutral points?

A long straight horizontal cable carries a current of 2.5amp . In the direction 10^@ south of west to 10^@ north of east, figure. The magnetic meridian of the place happens to be 10^@ west of the geographic meridian. The earth's magnetic field at the location is 0.33G and the angle of dip is zero. Locate the line of neutral points (Ignore the thickness of the cable). [At neutral points, magnetic fied due to a current cable is equal and opposite to the horizontal component of earth's magnetic field.]

A long straight wire in the horizontal plane carries as curret of 75 A in north to south direction, magnitude and direction of field B at a point 3 m east of the wire is

In the magnetic meridian of a certain place, the horizontal component of the earth's magnetic field is 0*26G and dip angle is 60^@ . What is the magnetic field of earth at this location?

A long vertical wire carrying a current of 10A in the upward direction is placed in a region where a horizontal magnetic field of magnitude( 2.0 xx 10^-3) T exists from south to north. Find the point where the resultant magnetic field is zero.

The horizontal and vertical components of earth's magnetic field at a place are 0.3G and 0.52G. The earth's magnetic field and the angle of dip are

A long, vertical wire carrying a current of 10A in the upward direction is placed in a region where a horizontal magnetic field of magnitude 2.0xx10^-3T exist from south to north. Find the point where the resultant magnetic field is zero.
