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 = μ
I / 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: A

Answer:
Energy remain conserved while converting its form from one to another
Explanation:
As per the conservation of energy, energy always changes its form from one form to another and it is neither destroyed nor created. The total amount of energy always remains the same.
There are several forms of energy such as thermal energy, electrical energy, nuclear energy, electromagnetic energy, etc.
For example –
During any chemical reaction, form of one chemical changes into another. In this process some amount of chemical energy remains conserved while the deficit in total starting energy is released as heat and light energy
