Question

(1)(A)What is the maximum force on a rod with a 0.100 µC charge that you pass between the poles of a 1.53 T strength permanent magnet at a speed of 4.52 m/s?

(B)A Hall probe calibrated to read 1.00 µV when placed in a 1.81 T field is placed in a 0.134 T field. What is its output voltage?

(C)Calculate the Hall voltage induced on a patient's heart while being scanned by an MRI unit. Approximate the conducting path on the heart wall by a wire 7.50 cm long that moves at 10.0 cm/s perpendicular to a 1.25 T magnetic field.

(D)What is the maximum torque on a 131-turn square loop of wire 18.0 cm on a side that carries a 57.0-A current in a 1.60-T field? What is the torque when ϕ is 20.0°?
