A magnetic field is produced by a current-carrying wire. The magnetic field strength at a dis\tance of 0.1 m from the wire is given by \( B = \frac{\mu_0 I}{2\pi r} \ \), where \( \mu_0 \) is the magnetic cons\tant, ( I ) is the current, and ( r ) is the dis\tance from the wire. If the current is 2 A and the magnetic cons\tant is \( 4\pi \times 10^{-7} \ \) Tm/A, what is the magnetic field strength at the given dis\tance?
