Earth's magnetic equator
WebTo produce the present field, the equivalent current must be a westward equatorial loop, as shown in the bar-magnet figure. In SI units the dipole moment, μ, for Earth is 8.22 × 10 22 A m 2 (amperes times square metre). Webwhere R E is the Earth's radius, B o is roughly 31,200 nT (i.e., the average field magnitude at the Earth's surface near the magnetic equator), and r is the distance from the center of Earth. As you can see, by the time you reach ~4 R …

WebCalculate the vertical component of the earth’s magnetic field at the equator if the horizontal component of the earth’s magnetic field is at B and the angle of dip is 60०. Solution: The horizontal component of the earth’s magnetic field, H = B e cos 60० = B B e х ½ = B B e = 2B The vertical component of the earth’s magnetic field, V = Be sin 60० WebThe poles of the Sun are different in several ways from the areas near the Sun's equator. The Sun has a magnetic field with North and South Magnetic Poles. About every 11 years, the Sun's magnetic poles flip - North becomes South and vice versa. This flip happens around the peak of the sunspot cycle, when there are lots of sunspots.
