'A long wire of a radius 0.55 mm passes through it a current of 1,2 A_ Calculate the magnitude of the magnetic field produced by this wire in reglon = 0.30 mm away from the center of the wire (r ='
Added by William R.
Step 1
We need to use the formula for the magnetic field produced by a current-carrying wire, which is given by: B = μ₀I/2πr where B is the magnetic field, I is the current, r is the distance from the wire, and μ₀ is the permeability of free space (a constant value). Show more…
