An electromagnet has 500 turns, and a current of 2 amperes flows through it. Calculate the magnetic field strength produced by the electromagnet using the formula B = μ.nl (where B is the magnetic field strength, H, is the permeability of free space, n is the number of turns per unit length, and I is the current).
