MAGNETIC FIELDS SUMMARY You will measure how the magnetic field, B, produced by a coil varies with the current, I, in the coil. From your measurements, you w calculate the permeability constant Ho. Lastly you w use a magnet to induce a voltage in the coil. THEORY The magnetic field Batthe center of a circular coil (solenoid) of radius R with N turns that carries a current...

21. Concept 26-7 gives the magnetic torque on a current loop with a single turn of wire. To achieve higher torques suitable for practical applications, motors use coils of wire with several turns. What is the maximum torque on a coil with 100 turns, area 9.0 × 10-4 m2, and current 2.0 A in the presence of a magnetic field of magnitude 0.2 T? Express your answer in N·m. . 24.
