Current produce is
Explanation:
Given:
Magnetic dipole moment of Earth,
Radius = r = 2350 km = 2.35 × 10⁶ m
To Find:
Current, i =?
Solution:
Magnetic Dipole Moment:
A magnetic moment is a quantity that represents the magnetic strength and orientation of a magnet or any other object that produces a magnetic field.
Magnetic dipole moments have dimensions of current times area.
It is given by,
Where,
= Magnetic dipole moments
i = Current
A = area =
Substituting the values we get
Therefore,
Current produce is
I couldnt type it out so here's a picture
