Identify the incorrect statement.
The electromagnets are used in-
“The magnetic field arises due to electric current produced by convective motion of metallic fluids in the outer core of the earth.” This statement is known as
Above curie temperature
Imagine you are standing on some point on equator, let us call it P. The geographic meridian and the magnetic meridian passing through P make an angle θ between them. If you walk half the earth on equator, and reach a point Q, then the geographic meridian and the magnetic meridian passing through Q make an angle ϕ between them, then
The magnetic dip on the magnetic north pole is
The magnetic dip on the geographic north pole is
Imagine you are standing on some point on equator, let us call it P. The geographic meridian and the magnetic meridian passing through P make an θ between them, then θ is
If you follow a magnetic needle, you will reach
A magnetic compass kept on the equator, free to rotate about the horizontal plane,
A magnetic needle free to rotate in three dimensions 
If the area of the hysteresis curve of the transformer cores is large, then it will dissipate:
The hysteresis curve for the transformer cores should be:
