Question

2. Define neutral points, show that the plotting of neutral points in both situations:
a) When magnet is placed with its north pole pointing towards north
b) When magnet is placed with south pole pointing towards north​

Answer 1

Answer:

What is neutral point ?

the temperature at which the thermoelectric power of two metals is zero and which is midway between the temperature of the cold junction and the corresponding temperature of inversion.

A) The magnetic field due to a bar magnet at an axial point is double in magnitude than that at an equatorial point. ... At an axial point, the earth's field and the bar's field will point in the same direction and hence add up. Hence, net field = 2BH+BH=3BH.

B) A bar magnet is placed north-south with its north pole due north. The points of zero magnetic field will be in which direction from centre of magnet.and please mark me as brainliest and please follow me
