Page of 2 ZOOM + OHMANN, UST PHYSICS B-FIELD: TORQUE 2) A single-turn wire loop 10 cm in diameter carries a 12-A current. It experiences a 0.015 Nm torque when the normal to the loop plane makes a 25° angle with a uniform magnetic field. Find the magnetic field strength.

For a solenoid in vacuum of length / 10 cm with 10* turns per meter calculate the value of the current if the solenoid is placed in an external uniform magnetic field Bext = 35 µT with field lines exactly opposite to the field produced by the solenoid. Take vacuum permeability µo 4r × 10-' H/m. Provide your answer in Sl units.
