Answer:
I will explain the concept of magnetic field and how it can be calculated.
Explanation:
The formula for magnetic field at the center of a loop is given as
B = μI / 2R
where B is the magnetic field
R is the radius of the loop
I is the current
and μ is the magnetic permeability of free space which is a constant 4π ×
newtons/ampere²
If the magnetic field at the center of the loop is 0, then μI = 0
I = 0 which means there will be no current flow in the loop.
Answer:
<h2>As per right hand rule the force direction magnetic field is along - z axis</h2>Explanation:
As we know that the force on the moving charge due to magnetic field is given as
here we know that
so we will have
so direction of magnetic field must be along -Z Axis
