Determine the value of the current in the solenoid so that the magnetic field at the center of the loop is zero tesla. Justify your 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.

root word, prefixes, and suffixes

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
