What is a neutral point? How is the position of a neutral point located with the use of a compass needle ?

At a neutral point

What is the principle behind a compass needle?

What is the colour code for the insulation on the neutral

A magnetic dipole of magnetic moment 0.72(sqrt(2) Am^2) is placed horizontally with the north pole pointing towards east. Find the position of the neutral point if the horizontal component of the earth's magnetic field is 18 muT .

A magnetic dipole of magnetic moment 0.72 Am^2 is planced horizontally with the north pole pointing towards south. Find the position of the neutral point if the horizontal component of the earth's magnetic field 18 muT .

A magnetic dipole of magnetic moment 1.44 A m^2 is placed horizontally with the north pole pointing towards north. Find the positon of the neutral point if the horizontal component of the earth's magnetic field is 18 muT .

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.]

What are the neutral oxides of nitrogen?

In a meter bridge the point D is a neutral point (Fig. 2(EP).4).

Explain the method of plotting magnetic field lines by using a small compass needle.
