You're on a roll — here's the solution for question 12: Given: Length of wire, L = 0.50 m Current, I = 8.0 A Force on the wire, F = 0.40 N The wire is at right angles to the magnetic field, so = 90^. Step 1: Recall the formula for the magnetic force on a current-carrying wire. The formula is F = BIL . Step 2: Substitute the given values into the formula. Since the wire is at right angles to the magnetic field, 90^ = 1. 0.40 N = B (8.0 A)(0.50 m)(1) Step 3: Solve for the magnetic field strength, B. 0.40 N = B (4.0 A · m) B = 0.40 N4.0 A · m B = 0.10 T The strength of the magnetic field is 0.10 T.
