A telephone cable at a place has four long straight horizontal wires carrying a current of 1.0 A in the same direetion east to west. The earth's magnetic held at the place is 0.39 G, and the angle of dip `35^@.` The magnetic declination is nearly zero. What are the resultant magnetic felds at points 4.0 cm below the cable?

The value of horizontal component of earths magnetic field at a place is 0.35 xx 10^-4 tesla. If the angle of dip is 60^@ , the value of vertical component of earths magnetic field is about :

A long straight wire along z axis carries a current I in the negative z direction. The magnetic vector vecB at a point having coordinates (x, y) in the z = 0 plane is

At certain place, the horizontal component of earth.s magnetic field is 3.0 G and the angle dip at that place is 30^(@) . The magnetic field of earth at that location

A long straight horizontal cable carries a current fo 2.5 A 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 0.33 G , and the angle of dip is zero. Locate the line of neutral points.

In the magnetic meridian of a certain place, the horizontal component of the earth's magnetic field is 0.26G and the dip angle is 60^(@) . What is the magnetic field of the earth at this location?

Two long and parallel straight wires A and B carrying currents of 8.0 A and 5.0 A in the same direction are separated by a distance of 4.0 cm. Estimate the force on a 10 cm section of wire A.

If the total magnetic field at the place is 0.56 G, then calculate the vertical component of Earth's magnetic field at which the dip angle is 30^(@) .

A 3.0 cm wire carrying a current of 10 A is placed inside a solenoid perpendicular to its axis. The magnetic field inside the solenoid is given to be 0.27 T. What is the magnetic force on the wire?
