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.

since you're a real machine, your ama is always less than your ima, because you can never totally eliminate friction.
